Why should I? Arent you the ones complaining about the current developments?
The active players of the community celebrate this DLC as one of if not the best. It is just the casuals and noobs that complain, either due to skill issue standing in front of the success they feel entitled to or their expectation, that teamplay in a multiplayer game is entirely optional.
Bold name btw, for a guy, who - just like pretty much everyone else complaining about Dual Destiny - hasnt done a single dungeon solo-flawless.
