That being said, I don't try to keep everyone at full. That's not my job. My job is to keep everyone standing. Don't ***** at me if your health drops to 50% or less, especially if your AOE broke my CC and you got reamed. Don't ***** at me because you're jumping all over the place breaking LOS. Don't make healing harder than it has to be or I won't go out of my way. Unless you're the tank, in which case I always follow your lead.
I wouldn't play a healer that did nothing but heal unless the fight required it. And IMO if you disagree feel free to get another. Especially annoying when you have to start cc'ing and some d.a. keeps breaking. That's 95% a dps though.
Like the others have said, sounds like a class queued as healer while dps spec'd.
