Just want to reiterate that if you're healing to the best of your ability and that's all you have time for, genuinely don't have time to dps because of damage or mechanics, no one's expecting the healer to dps at that point.

The expectation begins when the party isn't taking damage and the healer is literally just standing there while the tank is topped off by a HoT or pet.

If that's elitism, then it's not going to hurt my feelings to be elite.
