I think Hanzo is OP. He has a huge window for "sniping". It's not really sniping because he can dance around and still have a full field of view and the zone in which he actually hits his target is huge. Then, of course, he has his giant super ability with the dragon. If anything his window needs to be narrowed so he's actually, you know, sniping. Not hailing arrows in a direction and getting instant kills.
