Our instant proc's in the current game are the only thing keeping us in it. If we literally had to cast to do anything, we would be by far the worst class in the game right now.
I agree, I'm worried about losing instant proc's. Not because I find the play style fun, but because I'm not sure how well we'd do without it unless we get more changes somewhere else. I do enjoy playing my boomkin, but it could be better.
