Can't speak for any other healer, but I decide whether to DPS on a run by run basis. I come from WoW and raided during Wrath of the Lich King, so I'm more use to traditional healing. That said, I enjoy the way healers are here, especially for solo content / MSQ. If I find myself standing around a lot on trash, I'll look for opportunities to help if I can. But the party's health is my #1 concern and provided I'm not going OOM (which isn't a big issue currently as WHM) I aim to keep my group topped off; not wait til they're at 20% to throw 'em a bone. That style of play wouldn't work for me--I have vision issues and that would end in disaster. Anyway, just my thoughts. Different healers do stuff different ways.
