Like others have said, most the time it is the tank at fault. What I do on pull is, as soon as the tank grabs hate put regen on him + a card on tank/dps. Don't use DoTs if there is 3+ mobs, just jump right into gravity spam. Let the tank get real low, just watch how fast his hp is dropping to determine when to leave clerics. Essential dignity, with real low hp has huge potency. I've healed close to 10k with a crit using this. Follow that with an instant aspected benefic, then jump back into gravity spam. Killing big groups faster saves a ton of mp, and gravity spam with no interruptions can outdmg even aoe dps jobs.
