From what I saw at Blizzcon things are looking pretty damned good. Raiding is getting sorted out, PvP has some better casual elements (for those of us who only dabble from time to time in organized pvp and prefer other games for pvp), we're finally getting upgraded models (about damned time!), player housing was unexpected but the feature rip from Guild Wars (Trophies/Monuments), SWToR (Followers), and Rift (Building your own 'home') will be something interesting to do inbetween Mythic raiding.
However, the whole follower farming mini-game/tool seems a bit too....micro-managy I guess. I'm alright with having to level them but the whole "rarity" and "gearing" them thing seems a bit too much. This would be fine but the fact that you can get limited access to other professions and utilities via this method makes it seem a bit annoying. I dunno.
What do you guys think?
