Quite possibly the greatest source of information in regards to leveling I have seen for a new expansion. Bravo. Me and my friend are having a week long lan party at my house so we plan on leveling our mains to 120, doing all the week 1 shit and then starting at least another toon to get 120 as an alt (I personally am an altoholic, its bad, send help)
Literally just do quests as efficiently as you can. The difference between picking a perfect route and just doing whatever is like an hour, tops. I've already leveled 7 characters in bets because I won't be playing at launch (baby due in aug) and I've been under 12 hours on all but the first. I actually broke 10 on DH, but that's bcuz war mode and DH leech is OP, not because of a special route.
Usually it's best to avoid a lot of instance runs. It is too difficult to account for bad groups, and some instances are too far away with too few quests. Since the experience is very good, it's a good idea to clear nearby instances which have a lot of quests once (Gnomeregan, Deadmines for Alliance). Distant instances with few quests should be avoided (Deadmines for Horde). Low level instances can be cleared by paying or befriending a single high level character. However, since patch 3.3 a new Dungeon group finding system has been implemented, as well as a direct port to dungeons (when entering the group you get ported to the dungeon and back to the same location if you leave it) and thus the travel time to dungeons has been greatly reduced. This makes it a good idea to complete quests or grind while you wait for a group to become available.
But when it comes time to level another character for any reason, this pace is going to make me think twice. And that's a shame. I'm not someone who gets any particular joy out of instant-boosting a character to max level. There are dozens of zones -- no exaggeration -- that I wouldn't mind experiencing again, if I could do a few of them at a time and feel like I was making meaningful progress on another level-110 in the process.
Fourth, beginning in Mists of Pandaria with the Halfhill farm, and continuing in Warlords of Draenor with various garrison buildings that produced resources, Blizzard has been making trade goods more plentiful and easier to obtain. In Legion, herbs, fish and enchanting materials were so abundant that a very small population of gatherers could supply more raw materials than the economy could consume.
Do quests and complete the story of your first chosen area before returning to your capital to scrap all of the equipment items you acquired. You should be around Level 113 by the time you complete your first area. Before selecting your second zone, head to your faction hub ship to acquire your introductory quests to the mission table and your champions. Complete this introduction and then pick up the quest to establish your first foothold in enemy territory.
Prior to update 7.3.5 it was far too easy to level up a new character. The experience needed to advance from one level to the next was too low, resulting in players out-leveling the story quests in each zone, moving on before getting the full experience. With low monster health and high player power (especially when players were outfitted in ridiculously powerful heirloom gear), creatures dropped like flies. Combined with easy experience gained by joining parties in the dungeon finder, the first 60 levels in the game flew by.
The guide works great (of course expect a) BUT, after reaching 120 there should also be a guide to open and explore the remaining areas. Also, sometimes when multiple objectives are required, the guide forces you to follow in the order the guide prefers and if you don’t the objective is not rewarded. Gotta start catching up on the followers guides also. All in all, the $47 a year in-game guide is well worth it.
