How to Start The War Within

Upon logging into the game on a Level 70 character, you should receive a quest fittingly named "The War Within". This quest provides you with a teleportation scroll that goes directly into your bags, and you should right click on this item to use it.
The scroll will teleport you to Silithus, and this leads into the standard introduction questline which eventually takes you back to Dalaran. If you're reading this guide, you should have already fully completed the War Within Campaign and reached level 80 on a different character, so all of this should be familiar to you. If you are trying to level your very first character from 70-80, then you're on the wrong guide. You should instead use my 70-80 CAMPAIGN Guide, which can be found here.
The Dalaran introduction isn't very efficient for actual leveling, so I would recommend that you skip it instead. You can do this by speaking to Thrall or Jaina and selecting the dialogue option "I have heard this tale before". You'll then be teleported straight into the center of Dornogal.
You should find yourself standing close to Brann Bronzebeard, and by talking to him you can pick up the quest "Adventuring in Khaz Algar". This quest will direct you to interact with the nearby Scouting Map, and you can click on each zone to receive their associated breadcrumb quests. You'll always want to grab the Isle of Dorn quest, but it can't hurt to grab the quests for the other 3 zones just in case you decide to go there at a later level.

Adventure Mode Flexibility

Now that you've entered Khaz Algar, we need to take a moment to discuss Adventure Mode and how it affects the leveling process. By definition, this system allows you to level with any activity of your choosing, but not all activities are equivalent in their leveling efficiency. Every time I make one of these guides, I'll receive messages people telling me that I "forgot to include xyz activity in my guide". In 99% of cases the thing they're referring to is something that I had already tested and found to be inefficient, and so I didn't mention it in my guide.
To hopefully avoid some of these messages, I'm going to quickly run through a list of activities that I do not recommend doing while leveling:

World Quests: These are usually slower than normal quests and give less experience. Only complete them if they're directly overlapping a quest hub that is recommended by the guide.
War Within Dungeons: Spamming Normal dungeons was very fast at the start of the expansion, but it has since been heavily nerfed. This is now an extremely inefficient leveling method. The only time running dungeons isn't completely inefficient is if you're completing the one-time quests for Ara Kara or City of Threads. I still don't recommend doing this compared to the other activities in my guide, but it's not a terrible way to spend your time if you REALLY like dungeons.
Follower Dungeons: These can be a nice way to learn your spec in a pressure-free environment, but they are ABYSMAL when it comes to leveling. Follower dungeons have no RDF experience bonus, and the mob kills give slightly less XP than normal dungeons. This is maybe the least efficient leveling activity in the entire game, Pet Battling would probably be faster.
Timewalking Dungeons: Timewalking is a limited time event that rolls around every few weeks, and it allows you to queue for dungeons from older expansions that scale up to your level. Many people seem to believe that Timewalking dungeons are extremely efficient, but I've disproven this with countless test runs over the years. That being said, for people who really enjoy dungeon spamming, Timewalking dungeons ARE considerably faster than normal War Within Dungeons, and spamming them (generally as a tank) isn't that much worse then my standard route.
Player vs Player: You should usually level with War Mode on, as it provides you with a 10% experience bonus to all outdoor content. However, this does not mean that actually PvPing is an efficient way to level. World PvP will obviously slow you down and should be avoided at all times (unless you enjoy it, in which case go wild I guess). Instanced PvP is also terrible for leveling efficiency and I can not recommend it at all.
Pet Battling: I'm part of the ~1% of players that actually really enjoys Pet Battling. Unfortunately, it's complete beans for actual leveling.
Mob Grinding: You might find some guides online that advertise "overpowered mob grind spots", or some clickbait nonsense like that. Every spot that I know of is still slower than following my guide, and the players using these spots generally have extremely strong characters decked out with BiS gear from the previous expansion. This is not a realistic option for 99% of the playerbase, nor is it faster even when done correctly.
Azj-Kahet Quests: Standard quests from Azj-Kahet, including both Campaign and Side Quests, will not be recommended at all within my guide. This zone isn't terrible persay, but it's notably slower than the other three zones, so I won't be recommending any questlines from here. This does not include the Azj-Kahet delves and their associated Delver's Call quests, which will be discussed in the Delve section of this guide.

Lastly, it's worth mentioning that you'll gain an account-wide 5% experience bonus every time you level a new character up to 80. This caps out at 5 characters for a total of 25% bonus experience. Obviously, this means that the more characters you level up, the faster the entire process will become, and you'll be able to slowly trim out the less efficient sections of this guide with each additional character.
For example, the end of my guide will mention multiple side quest hubs within both Hallowfall and the Ringing Deeps, but I never actually did this in my current fastest run of 1 Hour and 38 Minutes. It's likely that you also won't finish every single part of my guide before reaching Level 80, but the section that you choose to cut is ultimately your decision. I've filled this guide with way more activities than you'll actually need, since I want to make sure it accomodates players with no experience modifiers, as well as people who don't want to waste gold on crafting.
For these aforementioned reasons, I won't be putting suggested level ranges on the various sections of my guide. Everything in Adventure Mode will scale with your level, so there is no "correct" level or range during which you should complete a specific activity. Generally speaking your character will have an easier time killing mobs at lower levels, but this won't have a noticeable impact on the routing for the vast majority of players.
That being said, I have ordered the activities in my guide from best to worst, so you can use that as a rule of thumb if you're not sure which activity you should complete next.

Profession Leveling

Back in Dragonflight, Blizzard introduced the ability to gain a large amount of experience by leveling up your crafting professions. In terms of time efficiency, this is extremely fast, as you can gain roughly 2 free levels in ~5-10 minutes. However, this leveling method also requires you to spend a decent amount of gold on materials, so it may not appeal to newer players or people who are particularly stingy with their spending.
The experience you earn from this system is tied to "First Crafts", which, as the name implies, is a bonus that you gain the first time you craft each recipe. There's a small indicator on the crafting window that tells you if you'll get a first craft bonus, and you're also able to sort your recipes to only show the ones you haven't crafted.
In total, you're able to earn experience from 30 different War Within first crafts, but a lot of this experience is also front-loaded. The final 10 first craft bonuses that you gain will steadily decrease in experience value, with the 30th bonus being worth very little. For this reason, you may prefer to only get 20-25 of your first crafts if you don't feel it's worth spending gold on the last few. After 30 first craft bonuses, any additional ones that you complete will no longer reward any experience.
While many people think that you should wait until the later levels (~77+) to complete these profession crafts, it doesn't actually matter that much. The first time crafts give a fixed amount of experience, meaning you aren't gaining any extra by waiting until the final level. Getting your crafts out of the way early on will allow your alts to equip powerful Level 71 Crafted Gear ASAP, and it also ensures that you don't waste any of this easy experience before you hit Level 80.
Another crucial thing to note about crafting experience is that it IS affected by many experience modifiers, such as the 25% Warband Bonus and the Darkmoon Faire Buff. The War Mode bonus notably doesn't work, as it specifically buffs quest rewards and mob kill XP. This also means that if you were to complete your first crafts in a specific zone that applies a blanket experience bonus, you could theoretically benefit from that modifier as well, which brings me to my next point...
There's a world event in Dragonflight zones called Dreamsurges, and this will be hosted in a different Dragon Isles zone every single week.

While you're within the active Dreamsurge zone, you'll gain a buff called Dreaming Winds, and this provides your character with 25% additional experience from all sources.
Dreamsurges also have a convoluted system that grants a temporary rotating buff which lasts for 30 minutes. If you don't already know how this works, I won't bore you with the minor details. All you need to know is that there is a small chance every 30 minutes for you to gain an additional buff that grants 30% bonus experience from all sources.
Both of these buffs stack with each other for a combined total of 55% additional XP, and they also stack with all other standard XP increases (Warband, DMF, etc). Keep in mind that these buffs only persist while you're standing within the Dreamsurge zone, so you would need to complete all of your first crafts without leaving whichever Dragonflight zone happens to be empowered.
On the surface, this may appear problematic, as you would normally be forced to return to your profession trainer to learn new recipes, and the constant back and forth between Dornogal and the Dragon Isles would lose you a ton of time. Thankfully, there is one profession that completely bypasses this restriction AND has an extremely simple path towards 30 first crafts.

When it comes to leveling efficiency, Enchanting is the best profession and it's not even close, and it's for the following reasons:

Enchanters can quickly and easily unlock 30 recipes for first craft bonuses, and most of these are obtained without the help of a trainer.
Because the majority of your recipes don't need to be learned at a trainer, you won't need to constantly return to Dornogal in between completing crafts.
Additionally, the vast majority of enchanting recipes don't require a workbench, which means you can craft them at any location in the world.
When you consider all of these factors, you'll quickly realize that enchanting enables you to complete almost all of your first craft bonuses within a Dragonflight Dreamsurge zone. This means you'll gain 55% additional experience from most of your crafts, granting you a ton of extra experience completely for free.

The only downside to this is that Enchanting tends to be one of the pricier professions to level, which, again, makes it a hard sell to newer players or people who don't want to spend gold. That being said, this guide will only go over the exact materials and steps for the enchanting route, as it's the only true option in terms of leveling efficiency.
If you do decide to use a profession other than Enchanting, I'd recommend buying an Ultimate Gnomish Army Knife off the Auction House. This is the easiest way to make sure that you have every normal profession tool accounted for.
As for enchanters, you should pick up a Runed Bismuth Rod, ideally with Crafting Speed as the secondary. You could also grab an Incanter's Shard for additional Crafting Speed, but this isn't really useful outside of the context of a speedrun.
Here is a complete shopping list for all materials that you'll need to complete 30 first-time craft bonuses with Enchanting:

And here are the exact steps that you should follow in order to get all thirty first-crafts while maximizing your Dreamsurge XP bonus:

Step 1: Visit the Enchanting Trainer within Dornogal. Learn the profession and the initial recipes.
Step 2: Spam the Gleaming Shatter craft until you reach exactly 22 skill. You will not gain a first-craft bonus from this, and that's ok.
Step 3: Speak to the trainer and learn any new recipes.
Step 4: Craft a Runed Bismuth Rod.
Step 5: Speak to the trainer and learn any new recipes.
Step 6: The trainer will offer a random quest that rewards experience and Knowledge Points. The required material is random, so I haven't included it in the shopping list. Buy it off the Auction House and complete the quest.
Step 7: On the Enchanting window, locate the "Specializations" tab at the bottom and click it. Choose "Ephemerals, Enrichments, and Equipment" as your specialization.
Step 8: Fly north and locate the main profession building. You should see a quest offered by Roldira called "Crafting to Order". Pick this up and complete it, the reward you choose does not matter.
Step 9: Speak to the nearby vendor named Lyrendal. Purchase the item Faded Enchanter's Research for 200 Artisan's Acuity, and then right click it to gain the Knowledge Points.
Step 10: Learn Illusory Adornment: Crystal from the recipe in your bags.
Step 11: Open your Enchanting Specialization tab once again. Put 5 points into "Ephemerals, Enrichments, and Equipment", and then unlock "Deceptive Decorations". Put all of your remaining Knowledge Points into Deceptive Decorations.
Step 12: Return to your faction's portal room in Stormwind or Orgrimmar and take the portal to Valdrakken. Locate the Dragon Isles zone with an active Dreamsurge and fly to it.
Step 13: (OPTIONAL) When you arrive in the Dreamsurge zone, you will always benefit from the 25% Dreaming Winds buff. There is a rare buff called Dreamsurge Learnings which grants 30% additional experience, but this is very rare and can take hours to appear. Obviously this will make your leveling a lot faster, but you could be forced to wait multiple hours for it to show up. Personally I would recommend waiting until the buff appears, but you could always do your crafts immediately if you're in a rush.
Step 14: Craft the followings recipes:

Glimmering Haste
Glimmering Critical Strike
Glimmering Mastery
Whisper of Silken Avoidance
Whisper of Armored Avoidance
Illusory Adornment: Crystal
Illusory Adornment: Runes

Step 15: Spend 15 Knowledge Points in the Deceptive Decorations tree to unlock every single Gleeful Glamour recipe.
Step 16: Craft every single Gleeful Glamour variant.
You should now be finished with all 30 first craft bonuses. You can return to Dornogal and continue to the next section of the guide.

Isle of Dorn

Whether or not you chose to start with Profession Leveling, you should now begin the Isle of Dorn campaign. If you followed the previous steps in my guide you should have skipped the Dalaran intro, so you'll need to fly west in order to reach Dalaran's crash site.
You'll begin the Isle of Dorn campaign by picking up "Slay the Saboteurs" from Jaina, and "Urgent Recovery" from Thrall.
Continue following the campaign quests here as you normally would. While completing "Stones of Dornogal", which instructs you to speak with multiple NPCs in the main city, you should set your hearthstone at the Dornogal innkeeper. This will save you a bit of travel time whenever you need to return here later in the questing process.
At the end of the Dornogal quests, you'll be directed to a town called Freywold Village. Before heading there, you should take a short detour south-east of the city to a subzone called Crossroad Plaza. Run around this area and pick up any quests you see, including the ones given by wanted posters. You won't be completing every single quest here, but it's easier to grab all of them now and abandon the ones you don't need later on.

The first notable quest here is called "Delver's Call: Earthcrawl Mines". This will be needed for when you complete Earthcrawl Mines during the campaign, more on this later.
The other two relevant quests in this area are "The Earthwound" and "Wanted: The Boroughbreaker". Both of these quests require you to kill a single mob, and both of these mobs are located fairly close by. You should complete "The Earthwound" first, and upon killing the mob you should immediately turn in the quest. The Boroughbreaker should be killed as you travel south towards Freywold Village, but you won't actually hand in this quest until later. The turn-in point is within Dornogal, so you'll just complete it the next time you return to the city.

Shortly after arriving in Freywold Village, you'll be directed to speak with Brann Bronzebeard and complete the Earthcrawl Mines.

When you complete this delve within the campaign, you'll also get credit for the aforementioned "Delver's Call" quest. This gives you ~90k experience completely for free, which is why it was important to grab that quest earlier.
You're supposed to be able to pick up these Delver's Call quests within the delve itself, but this is currently bugged for the campaign version of Earthcrawl Mines and it doesn't actually show up within the delve.
Completing this delve as part of the campaign will guarantee that the "Kidnapped Earthen" story is active. This is the fastest potential story for Earthcrawl Mines, so completing the delve during the campaign is ideal.
The next section of this guide will go into a lot of detail about delves and their place in the leveling process, so I won't repeat that information here. You can skip ahead and read that section now if you want to learn more about how to optimize this initial delve.

The route has been fairly linear up until this point, but now you'll be presented with mutliple options. You can pick up the next few quests within the campaign, but you'll want to complete most of them alongside additional side quests which I'll discuss in a moment. Once the campaign directs you to leave Freywold Village and head north, you should stop following it, as things slow down immensely from that point onwards.
After picking up the campaign quests "Building Blocks" and "A Natural Remedy", you should run around Freywold Village and grab every side quest that you encounter.

"Prarie Fever" should be completed immediately, as it grants you two follow-up quests, "Buried, Not Forgetten" and "Monsters in the Dark". Both of these quests can be completed alongside the campaign.
"Weapons and Warriors" should be completed once you finish all of the campaign quests within Freywold Village. It will direct you to a different subzone in the east which is very efficient.
"All Ore Nothing" will direct you to a third subzone, but you shouldn't worry about this until later on in the leveling process.

Once you've completed the campaign quests up until "The Proscenium", you should finish "Weapons and Warriors" and complete all of the quests in the Glimmering Shore subzone. This area contains a bonus objective that isn't visible until you begin the questline, making this hub extremely efficient for leveling.
When you're finished with all of the quests in this hub, fly north and complete the chain in the Boskroot Basin subzone, which is located just outside of Fungal Folly, another delve. You may want to complete Fungal Folly at this point to minimize your travel time later, but this depends on factors I'll discuss later in the delve section.
Fly to the west and turn in "All Ore Nothing". Pick up all of the other sidequests in this subzone, The Opalcrag, and complete all of them.
You'll eventually be directed to a hub in the east called Golgrin's Reach. Fly there and complete all of the remaining quests in this chain, as well as the nearby bonus objective. The questline technically continues beyond this subzone, but you shouldn't follow it beyond this point.
Stop by Crossroad Plaza once again to hand in your completed Delver's Call quests. You should then fly a bit further to the north until you reach a subzone called Fallside Outpost. Start the quest chain here with "Before I Depart", and complete every quest up until "One More Tradition".
The delve Kriegval's Rest is located nearby, and you may want to complete it at this point. That being said, Kriegval's Rest is one of the less efficient delves, so you may opt to skip it instead.
Far to the north you should find a subzone called Rambleshire, and this area has a ton of efficient quests. Complete every quest you encounter up until "Thunderhead Butt", as that final quest has a lot of roleplay and isn't worth finishing.
There are still a few other sidequest chains within Isle of Dorn that aren't terrible, but the ones I've listed out above are all extremely efficient and should be prioritized. Once you complete all of these recommended side quests, it's generally a better idea to begin running delves instead of staying in Isle of Dorn.

Leveling Through Delves

Delve leveling has been a divisive subject since the launch of The War Within, as they were initially extremely inefficient and not worth completing at any point. However, Blizzard has since massively buffed the experience rewarded by the Delver's Call quests, and this has singlehandedly turned delves into one of the best methods of leveling.
Just to recap, each Delver's Call quest can be picked up at the start of its associated delve, and it only requires you to get completion credit for said delve. Each of these quests rewards you with a massive chunk of experience that is roughly equivalent to completing an entire dungeon. This is notable because most low level delves are extremely fast and easy to complete, making it very efficient to do each of them a single time in order to earn the experience from this Delver's Call quest.
In case it wasn't already obvious, this means that you should NEVER spam delves as a method of leveling. The actual experience earned from mob kills, while not terrible, isn't nearly enough to justify the time spent. You'll only want to complete a delve while leveling if you have yet to finish its associated Delver's Call quest.
Also, while the tier in which you complete the delve doesn't make a massive difference, I've generally found that running on Tier 2 gives you the best results.

The highest you can go while leveling is Tier 3, and increasing the tier will buff the mobs' health and damage, but also increase the amount of experience that they reward.
However, Tier 2 gives you 10% additional mob kill experience when compared to Tier 1, whereas Tier 3 only provides you with a 15% bonus overall. Again, the differences here are very trivial, but the jump from 0% -> 10% is obviously far more significant than a jump from 10% -> 15%.
Considering that the most important factor for delve leveling efficiency is completion time, since the Delver's Call quest is the bulk of the experience earned, it doesn't feel worth it to increase the difficulty to Tier 3. This causes mobs to die slower, and even though they're rewarding you with slightly more experience, you're also taking longer to finish the delve, which reduces your efficiency in the long run.
This isn't an exact science, as creating a perfect way to measure the difference in completion time vs mob kill XP is nearly impossible. I simply did many test runs on every single tier, and running it on Tier 2 felt more efficient, so that's what I'm recommending.

I'm sure many of you are wondering how much of an impact Brann makes on your leveling speed, so I'll take a moment to touch upon that.

Simply put, Brann is nearly worthless at his current tuning. While you're leveling up Brann's scaling is so abysmal that he'll usually contribute next to zero damage in a delve. Even at his maximum level, 60, Brann barely has an impact on the overall delve completion time. I recently got my Brann up to max level and made a video showcasing just how worthless he is in a variety of different scenarios. If that sounds interesting, you can watch it here: https://youtu.be/XyZHnDKw61Q
When it comes to Curios, you should ideally have all of them at Epic quality, as this does increase their effectiveness for your low level characters. If you haven't gotten all of your epic curios yet, just make sure to run Tier 8 Bountiful Delves on your main whenever possible, and you should receive all of them before long.
For Combat Curios, the only viable choice is Porcelain Arrowhead Idol, as this boosts your damage as well as Brann's. The uptime on it isn't super high, but you'll get more value out of this than any of the other curios.
You have a bit more flexibility with Utility Curios, as I would recommend either Streamlined Relic or Amorphous Relic. Streamlined Relic gives you a bit more movement speed, while Amorphous Relic generally provides you with a larger damage bonus. Either is fine, it's down to personal preference.
Even though Brann's damage contribution is extremely low, you should usually still set his role to DPS, as this will give him a higher uptime on the Arrowhead Idol debuff. That being said, if you find yourself struggling with survivability, you could switch Brann's role to Healer.

The most important factor to consider when running delves is which story variant is currently active. A delve's active story is randomly selected every single day during the daily reset.

Some stories are extremely fast and can be finished in 2-3 minutes, while others are very slow and can take 5 minutes or longer. Each delve has 3 different variants (except for Underkeep which has 4) and that brings us to a total of 37 different delve variations.
Now, obviously I would need to be insane in order to thoroughly test all 37 different variations just for the purposes of this guide, but, luckily for you guys I don't value my sanity, so that's exactly what I did. If you want an excruciatingly detailed breakdown on which delves are worth completing for leveling, I've posted an hour long tier list video on my second channel, and you can watch it here: https://youtu.be/SHcbVy-TvPo

Of course, I don't expect that most of you will want to spend the time watching that entire video, so here's a quick summary:

Earthcrawl Mines should always be completed alongside the Isle of Dorn campaign. This was discussed earlier in the guide.
Fungal Folly should only be completed with the "Lost Miners" story, as the other two are exceptionally slow.
In the video I stated that Kriegval's Rest should never be completed as the experience from its Delver's Call quest is bugged. This has since been fixed, but I would still recommend avoiding this place most of the time.
Waterworks should be completed with the "Captured Engineers" or "Stomping Some Sense" variants.
The "Smashing Skardyn" variant of the Dread Pit is the most efficient delve in the entire game. There's a niche strategy that involves spamming this delve and farming mob kill experience within it, but it's not actually faster than my route. The other two Dread Pit variants are fairly good as well, so you should always run this delve.
All variants of Skittering Breach are extremely fast, so you should always complete this delve.
Mycomancer Cavern is very slow, and you should avoid running it in the vast majority of cases.
The Sinkhole is only worth running during the variant "Raen's Gambit".
All three variants for Nightfall Sanctum are rather slow, so this delve can usually be skipped.
The Spiral Weave is pretty mediocre, but none of its variants are terrible. If you've finished all of the good delves and aren't level 80 yet, this is the next delve you should run.
Tak-Rethan Abyss is one of the fastest delves, especially with the "Pheromone Fury" variant. You should always run this at some point before hitting level 80.
Underkeep has 4 variants in total, and 3 of them are trash. "Evolved Research" is the only decent variant, but you only have a 1/4 chance of seeing it every day.

In a perfect world you would obviously have access to the best version of every single delve on the same day, but this is unrealistic. In practice, you'll need to poke your head into the delve in order to see which story variant is active, and then you can decide whether or not that delve is worth running.
Obviously I will only do my speedruns on days where the majority of delves have ideal variants, but this may not end up being the case whenever you decide to level your characters. Ideally you should have reached atleast Level 75 after finishing everything in Isle of Dorn, and you may even be as high as Level 78, which is where I was in recent Devastation Evoker run. In either case you could easily reach level 80 from this point just by running every delve a single time and turning in the Delver's Call quests.
However, if you're still not Level 80 after finishing the "good delves" (Earthcrawl, Dread Pit, Waterworks, Skittering Breach, Tak-Rethan), you may prefer to do additional side quests instead of running the remaining delves with a crappy story variant.

Recommended Side Quests

At this point you probably won't need too much more experience in order to reach level 80, but there is a lot of variance due to the warband experience buff, so I'll provide with multiple options just in case.
If you've just barely reached Level 78 or you're somehow still at a lower level, you should head to Hallowfall and begin the campaign. As you progress through the campaign, you should grab every side quest that you come across, but you'll only want to complete them when they're already close to a campaign objective.
Generally speaking, Hallowfall is the second most efficient zone for leveling in The War Within, falling only slightly behind Isle of Dorn. The key difference is that a lot of Hallowfall's efficiency is backloaded, as Mereldar has a ton of side quests that can be efficiently completed alongside the campaign. Unfortunately, you won't actually get there until the very end of the Hallowfall campaign, which means it's difficult to justify leveling in this zone if you're already super close to Level 80.
If you want more detail on the exact side quests that you should prioritize within Hallowfall, I'd recommend reading that section of my campaign guide, which you can find here. The Hallowfall Campaign route for first time characters includes all of the most efficient side quests, so it's still a solid option for alt leveling.
Another great option is the start of the Ringing Deeps Campaign, and I would recommend this if you're much closer to Level 79. The campaign in this zone is the exact opposite of Hallowfall; all of the best quests are front-loaded, so even if things slow down later on, you should have ideally reached Level 80 by that point.
For the most part you'll just want to blindly follow the campaign within the Ringing Deeps, but there are two notable side quests within Gundargaz that you should complete. These quests are named "On Cold Dark Wings" and "Discarded and Broken". The latter quest will also provide you with a few follow-ups that you can complete before progressing further in the campaign.
Lastly, I mentioned earlier that all of the remaining Isle of Dorn questlines are still solid, but they aren't quite worth doing before you start running delves. If you find yourself extremely close to reaching Level 80 but you don't have any efficient delves left to complete, it may be worth finishing one of these bonus Isle of Dorn side quest hubs instead.
Even if you skipped most delves and opted not to get any profession experience, it should be mathematically impossible for you to not hit level 80 after finishing all of these side quests. If for some unbelievable reason you are still not Level 80, you should begin clearing the less-efficient delves until you get there.

Some Closing Thoughts

I've been thoroughly testing and refining this route since the start of the expansion, and I've leveled countless characters from 70-80 using it. Additionally, my 1 Hour 38 Minute time on Devastation Evoker is the fastest run that I'm aware of, but I'm sure I can push it even lower on a spec that I'm familiar with, such as Guardian Druid.
That being said, the expansion is only ~2 months old at the time of writing, so it's impossible for to have thoroughly tested every single piece of content in the entire game. It's totally plausible that I've overlooked an extremely efficient method of leveling, and this route may change in the future as a result of that.
Additionally, Blizzard tends to add world events in the middle of an expansion that have some influence on leveling. A great example of this would be the aforementioned Dreamsurges, which were added in Patch 10.1.7. We're still using that event for leveling in The War Within, so it's obvious that many of these mid-expansion additions can end up having a major impact on the route.
I'll do my best to test this new content as it rolls out and update the Adventure Mode guide accordingly, but for now, I'm confident that the above route is the fastest way to reach Level 80.
