Wow. I found this thread just browsing around, and I'm having a hard time believing that there are healers who think they shouldn't DPS, and enough of them that there is a controversy, and an actual argument.

How much of the existing game content can you get through solo without DPSing at all? Thats exactly how much group content you should do without DPSing. A quick scan of the tank forum doesn't show any nonsense arguments about tanks not DPSing. Why should healers get to be so lazy? You want to just heal and nothing else, play by yourself, see how far that gets you.

The whole concept is nonsense, the game gives you offensive spells. Who gets in a group and honestly thinks to themselves "I could contribute more, but nah, I'll just let these other people work harder instead". Pathetic.
