i think some saying is more the actitude of many players around DPS, i mean no matter how you mitigate place and agro a boss even to a level to make the healer don heal you at all, if you DPS is low compared to going full DPS mode then you are bad, some times with a friend we go MT full dps mode, with zero mitigation and recive a lot of comendations for that, you can make healers life a hell is you dealt dps you go to be good, i not say this is correct or the form to be good, i mt and do dps bcs is the meta how required, but is pretty sad healers and tanks be judge by so many dps dealt in the encounter, and i hope they make a balance to the players feel rewarded by they tank/healing skills more that how many personal dps they do.
