Use unleash more, before abyssal drain it's your best spammable aoe damage. The amount of unleash you use is dependant on the number of enemies, and how much mp you have. Don't Mark targets, most dps I play with ignore them so don't bother. Focus on aoe hate. As far as prepulling that sucks but if they get hit once or twice IT'S THEIR FAULT pull hate as soon as you can, but some people are in such a rush that they insist on setting the pace of the dungeon
