3 mobs? I don't really care what the DPS does. The only way I'm pulling only 3 mobs is if the dungeon layout forces it. That changes at 5+ mobs. Nothing annoys me more than when I pull 2 or 3 groups together, then spot that DRG sitting on 90% TP, calmly going through his single-target rotation on one of them. I immediately know this is going to be a slow dungeon.
