Sometimes I click off my cd just to wipe the party, and tell healer: heal me or no big pull, choose; to dps: kill them before I die or no big pull, choose. The I play properly until the near death experience happens again for the SAME reason. Mistakes can happens and understandable, I rather have a weak healer that straggle a little than a green icon dps.....and btw... just put your dots on and heal and if dpses are doing the job properly, the tank won't even need a huge heal because mobs are already dead.
