One more thought on the hunter class. Every time I throwing knife someone in the face in the crucible and they do not die it is sort of a buzz kill. I mean it is pretty difficult to land a good hit with the throwing knife so why not give the person throwing it a kill for hitting someone in the head with it. It is hard enough to hit someone in the body at times in the crucible. The warlock special melee attack kills me in one hit and that is obviously much easier to land than a throwing knife.
