There are a metric shit ton of quests that are unfriendly to boxers this time around. The game seems to be moving in a direction where the player interacts with the world more and more during quests and dungeons. The way it is being handled though is atrocious for us. It isn't group wide. All personal to each character.

That with the suspensions coming from PvP? I don't know if I'd bother in your shoes. If you bought MoP already well... may as well come back.
