My only complaint is that the grind is never ending. If I log onto an alt and do a dungeon, that's a dungeon that I could have done on my main that had a chance at dropping gear higher than my heroic EN gear.
I always liked the idea of having X things to do each week and being able to do those and be done.
I guess they're moving away from that and want that constant, grind as much as you want D3 style.
