This is the way to go if you're planning on clawing him, and you don't pray protect/reflect anything just soulsplit (At least I think so, I can't rewatch the vid due to crappy college wifi) and hope for good hits.
that shows basically what you'll want to do. My point is, I doubt I could get him from full to half, and I don't want to melee him any leftover health, so I was thinking on ranging half, and then switching quickly, veng, put up and claw spec. Or do claw spec first...but second would be better because of healers.
