Some people have made arguments that quest blues can sometimes be more powerful than heirlooms, especially with sockets. I'm not convinced. The simple fact that you never have to even look at quest rewards will save a non-insignificant amount of time over the course of leveling. Also of consideration is the value of enchanted gear never having to be re-enchanted.
-Island Expeditions- Island expeditions was one of the new features I was looking forward to but Blizzard no longer makes games that are ready when they are ready but rather makes games ready when the deadline comes. Thus, many of the new features are completely stripped down from what was expected and it's literally just a small scenario you enter with two other players to continue to grind out your Azerite neck piece.
If you’re jumping back in for Battle for Azeroth, we recommend checking out the big “what to do first” guide from Wowhead. You’re also going to want to brush up on specific advice for your class—both Icy Veins and Wowhead have incredibly detailed guides for all of the game’s combinations of classes and specializations. Make sure you go in and figure out all the new (or changed) talents you’ll be using, and start to memorize a typical combat rotation so you don’t die nearly as much in game’s latest incarnation.
Battle for Azeroth’s War Mode puts you into PvP mode and grants you 10 percent extra experience. But since the two factions will mostly level in separate zones entirely, you should almost definitely have this on when you’re leveling. That said, if you start getting killed by random PvP players consistently, stop using it. Although 10 percent is nice, it’s not worth dying every few minutes for.
Hopefully, you have a good idea how you want to begin your endgame experience in Battle for Azeroth. A whole new set of content will drop on September 4 when the Uldir raid opens up and the PvP season begins. That also marks the beginning of Mythic+ dungeons in BfA. Even after that happens, many of these tips and strategies for gearing up will still be the best sources of early gear for your new 120 characters.
“It’s challenging for sure,” said Cobo. “but I think that, ultimately, we have to look at what’s at the core of the faction [...] Everything is about honor when it comes to the Horde, and as the story unfolds and you start to learn about the motivations behind Saurfang, or the motivations behind Sylvanas and why she’s doing what she’s doing, it starts to create a perspective around, ‘Is that the kind of person that I want to follow?’
Make sure you have the two Flight-Path toys purchased, as this can save you time. It won't have EVERY flight path, but will have major locations for faster travel if you need to switch zones entirely(which you will). If you buy the toys on one faction, it unlocks for the other faction as well. So don't spend double the gold! These toys can be found at the heirloom vendor(Undercity for Horde, Ironforge for Alliance)
If you’re a returning player, consider paying for a month’s worth of playing time—a mere $15—and using the game’s newer Class Trials to see if you still have that spark for higher-level play. While you can also go the “Starter Edition” route for a free, limited romp through Azeroth, you might need a little more than the newbie zones to help you decide whether you want to play through the game’s latest expansion.
Anyway both got to 110 at around 50h played. I messed up with my Pal by going to Legion once I hit 100 instead of finishing treasures and bonuses in WoD. All in all, if I picked the best zones and was only trying to level as fast as I could, I would probably could have done it in roughly 40h. Note that it would have a been A LOT faster with a Monk as both Ret and Rogues don't really have a decent AoE until 40+ (45 for Ret and 63 for Rogue I believe). The daily also helps a lot. I know that leveling my Monk before the pre-patch was insanely fast. Might be slower with the changes to FoF, however.
