I'm also a ps3 player. While I have no idea what my actual dps numbers are, I've been complimented many times by those in the know. I really can't say what I do differently, only what I do. Like mentioned above, I always keep my dots up, I spread them out when applicable, basically just zero downtime. I always queue up my next ability right before the prior is finished, always use food, and always use potions at the right times in dps checks. Little things like these really add up over the course of a battle/dungeon.
