The idea that we need to DPS must go.

Your CORE role is finishing the dungeon, not standing around with a thumb up your butt for the 90% of the encounter that requires zero healing.

That would be your core objective, my dearie, not your core role. And no dungeon or raid that I know of requires healing for only 1/10 of the duration of any given battle. Or do you just constantly expect perfection from total strangers?
