If ur gonna use that phrase a lot u might aswell be a dps lol.
At least the run is still salvageable if you die cuz when shit goes down as a healer or tank, you know the run is dead due to being too low hp ( for tanks or healers trying to reach hp check ) or healers going oom due to being dead. Only applies if ur group isn't geared to the teeth lol.
Imagine any group with 70% of ppl meeting minimal ilvl entrance.
