I love the Legion zones, the artwork, the "feel" of the expansion.
I still strongly disagree with the ability prune, and the hunter class in particular - my former main class - seems outright ruined. I'm leveling a boosted 100 ww monk that I've never played before just because with any of the classes I've played before, I keep thinking about the abilities I enjoyed that have been lost.
So I think they need a total overhaul of the class design team, but, that aside, I am enjoying the new expansion much more than I thought I would.
