Well I guess your mileage may vary, but as dps players, most of us don't have the option of speccing heals. You as a healer solo queuing could push the envelope the other direction I suppose.
for normal standards, yeah. I mean I can switch off and be a solid DPSer if need be, but certainly far from a game changer. Best I will get out of my damage dealing for a full zone is around 200k, assuming I am still trying to assist in healing.
Still, when I load into a zone with two operative healers who do zero damage, I mean, you have to pick the best option available. Just means I'm 10-15 seconds behind everyone else at the start as I respec and refix my UI/keybinds.
