I feel as if he will need a nerf. I made a post about possible ideas for that here: http://us.battle.net/forums/en/overwatch/topic/19876317450
Would appreciate feedback.
Right now he plays as a better Tracer with a more viable long range poke and vertical dash. It's fun playing as him but very not fun dealing with him. I think a general consensus is that he is just a bit too good, so I propose the following:
A) Keep all abilities and stats as is with the exception of lowering his base health to 125. Since he can do Tracer's harass and "keep away" role better with the added ability to block and reflect most damage, this makes the most sense to me. His ability to counter and escape would pair well if he were more "squishy." With this build, ulting should overheal him back to ~200.
B) Lower base health to 150 and add fall off damage to counter his ability to harass from such a long way away. He keeps his awesome movement (which makes him most fun and most annoying) but he is forced to use that movement to get him in and out of his "effective" zone. Putting him more at risk if he wants to be most effective.
C) Do nothing, wait for teams to find a better composition to deal with. He is just a few days old in the beta, so I recognize the possibility that teams simply havent found his best counter yet. I doubt this, but it's a possibility.
