I don't know. I was one of those that would spend hours on Curse installing addons but then I would go as healer on a fight and healbot turned that role into the most pathetic boring crap I've seen in that game. The problem was that everyone raiding used it so Blizzard didn't have a choice but to tweak fights so it would take that addon into consideration to keep healing hard. It turned healing into this furious click mashing on name bars.

I mean I like addons but I sure as hell like healing in this game much more than on that other one.
