His E and Leap are overtuned. E has no drawbacks at all. You can just finish off a low hp target or melt a tank with it. Reduced damage? Screw that idea when you can follow up another arrow. Don’t get me started when he’s also damage boosted. Leap has a very low CD for a mobility. Sure the distance is quite short but that distance alone can save Hanzo’s butt on regular occasions.
Both issues make him ridiculous. Make him stand still while using E (but make it cancelable) and nerf leap’s CD. There are so many reasons why he’s so viable and his ult is just the cherry on top due to Rein/Zarya being viable again.
