just had this the other night

i pulled a pack and had aggro and the DPSer ran in front of me and pulled the next pack of mobs. I simply told my wife (the white mage of the group) "don't heal xxxxx and don't rez him", causing the DPSer to die and run back. Guess what that dps DIDN'T do the rest of the dungeon?

if you said "attack things that the tank didn't" ... you would be correct.
