I don't know why you're so negative about Mescaline. We might not be the damage-dealers, and we might not be required for any instances (except Tranq. Shot in MC) but if played right we do a damn good job. I've saved priests many a times when they have aggro. I can't talk about end-game, but at 51 I can solo mobs two and three levels higher with ease.
Sorry if I sound a bit, um, aggressive. I'm just touchy about the whole Hunters = crap argument, read that much on the forums it's like an automated response
