It looks like the main purpose of this weapon is to further enhance your overall health. I am getting to the point where I can survive the previous one shots from certain bosses by having high armor and hp combo. I try to find a balance between armor and hp usually with higher hp being the priority. We still do not know the damage of this weapon but if its like the pavise we have nothing to expect. Can't tell about the proc but the pavise is pretty hard to beat. I think it would be a lot nicer with a taunt proc. Doesn't look as cool as Pavise imo. As a primarily elite tank I was hoping for more then this but time will tell how good the procs are or aren't.
