I will take the other side. I am the one with lousy DPS. I am more casual, I dinged 70 late, I dinged 80 late. After most at finish Sunwell, I finished kara. Two things, I was trying to get in the right place and listen to everything one must do, and then try and kill stuff. I don't know the ultimate rotations, and only use half my spells, lucky to those used. My gear was poor, and talents were mixed up mess. I would listen and read, but it still takes alot of time.
