When Blizzard hits something with the nerf bat, it hits it hard. Genji lost his melee-into-dash combo, his Dragonblade went from 8 seconds to 6 seconds AND he can't double jump from walls anymore.
2 of those nerfs would be a hard hit, but all 3 sounds excessive. I'd be surprised if Genji is still popular after that.
I can see Blizzard vision there thou, specially with the double jump nerf. Genji was doing stuff he was not supposed to do, at least not on Blizzard initial design.
I'd be surprised if he is still picked after that though. He is still a high risk hero but I feel the reward is not there.
On the good side, Mei got buffed. Horray! :D
