I do love the throwing knife. The Titan might get a damage boost, but the Hunter is the only one who can get a critical hit with a melee plus he can do it at range. Those quick throwing knifes always catch people off guard lol... love. I think I will like the Arc Grenade quite a bit. Mainly for the Blink Combo. In my mind I see me blinking in, dropping the Arc Grenade to begin chaining lightning, blink strike to go invisible, blink to targets with shotgun, blink out. All based on speed. This is aside from supers of coarse. Also, I really like the idea of blink getting me out of the kill zone of Nova Bomb and Fist of Havoc. Once I see them go up I am totally "blinking" out of there lol.
