It's not really about scratching the vanilla itch.
This is a new, unsolved game that has a lot of new things to see and experience. New dungeons new quests new raids and a fuckton or new items. Different class core mechanics, and they are not bound by the "no change" policy of classic so I expect the meta in this game to be completely new and different.
A lot of good qol, and the new items for the most part include a lot of new designs and flavor that feel.....really good
The world looks absolutely fucking beautiful as well.
It's still the classic world we know and love, so the nostalgia is there, but with the promise of so much more.
If you follow these forums you know I shit on blizzard very often for the stupid shit they did over the years in wow retail, that shit is an aberration.
But they got me with this, they got me real fucking good, I haven't been hyped for a game like this in a long time.
