For reference, my previous best time abusing Method-0 in 7.3.5 was 32.4 hours(as show in the old thread). A difference of just over 8 hours; which isn't all that bad, all things considered. And I believe I made several errors along the way, which could be cleaned up in future runs. I believe that that gap could be significantly closed by using a monk's bonus, but I hate playing monk...so...yeah. YMMV
One of the very cool things about Zygor’s Guide is that it’s automated. Not only do you not have to manually switch from game to guide, you won’t even have to click to the next quest. Complete a quest and the guide will automatically update to the next quest. The guide does it for you (usually, sometimes you’ll have to click to the next quest on your own.) It really is like having someone giving advice over your shoulder. Here’s the next quest, here’s what you need to get…
The leveling path was built around using a Hunter character and run by a player who knew how to use that character well. For the average player running, for example, a Paladin, the guides could be frustrating in spots, due to the level of the mobs. I played through Joana’s Guide with a Rogue (all the way from 1-70) and was able to deal with most everything, except for a few elites and I skipped most all of the group quests.
/way commands like /way Shadowmoon Valley:Draenor 50.0 31.2 Ashlei don't work correctly. According to the way TomTom works, this waypoint should be created in Draenor's Shadowmoon Valley. Instead, it will be created in Outland's Shadowmoon Valley. So it seems there is currently no way to distinguish between zones that occur more than once with the same name, such as Shadowmoon Valley or Nagrand.
Despite all of these problems and this laundry list of glaring systematic issues, the crowning achievement of Battle for Azeroth’s endgame is that it still remains enjoyable all due to those two pillars of raiding and dungeons. That won’t last forever. As the expansion goes on, and the grind necessary to progress becomes even more demanding and the time spent in content that simply isn’t fun increases, it will be harder and harder for raiding and Mythic+ to carry the expansion along.
The world quests aren’t necessarily bad, but they aren’t good either. I wouldn’t mind killing five of a type of monster or fighting one particular boss a few times, but after seven or eight, it starts to wear pretty thin. But going from levels in the mid-20s can take nearly 30,000 AP, so you’ll need more than world quests if you want to get your heart up in a reasonable time.
