Keep in mind that Ana’s nade is not just for anti-ing enemy heroes. It’s a source of healing and defense for her against enemies diving or flanking her and a way of saving a teammate from a critical situation. Ana can nade multiple enemies at once, and Kiriko can cleanse multiple allies at once. Those cooldowns seem kinda fair.
Also, Lifeweaver didn’t deserve such harsh nerfs, the main reason he heals too much is because he has been designed as a healbot since he doesn’t have the same disruptive potential as other supports.
In every game I play, Shift to move forward, regular A, D for left and right and S backwards. In Overwatch I have Q first ability, W second ability and E for ultimate. WASD literally makes me feel dizzy.
