[@Sodomite], [@Dead Cruiser]: I have a lot of the same concerns, though my notes on everyone's profiles are a little too snarky to be posted here : P

But my overall consensus on the abilities was that he had an Instakill for Omnics, Humans, and support tech, while having essentially an ultimate as a weakness, being unkillable, and having a weapon whose only penalty (not cutting through shields and armor) was not a penalty at all because he didn't have teammates that would be affected by armor still on an opponent who managed to live to get away. 

I think something important to remember is that everyone else only has ONE LIFE in this RPG, versus the actual overwatch game where you can just respawn. That's crippling when the number of ways in which someone can instamurder you is at least threefold, if not more.
