DPSing as a healer got nerfed so bad at 60, at least on SCH, that I stopped trying, yeah. Going full throttle with Cleric's Stance I was still only contributing 2-3% of the damage, and that comes with a risk of not being able to save the tank in an emergency.
So now I'll throw up a token Shadow Flare and a Miasma II (since the debuffs from that help even if the damage is nothing) and focus on keeping everyone topped off and protected instead.
