Yeah it's pretty cool, dude. I'm killing it on demon hunter right now. It kinda sucks stuck at 100 though, not gonna lie to you. Two talent points is not great in pvp. No snares, self heals, anything. Buuuut when legion actually launches they get their full kit, so they'll be more viable. Unless you roll vengeance, then you're just a tanky healy beast that melee cringe at having to fight.
Yeah DH is pretty strong in random BG's ..they mostly top the meters and will get a nerf before too long my guess. Fun to play while they are op tho.
