And if he breaks 50%, we get stuff like the 77% ban rate in plat+ he has now.
Maybe someone at Riot will eventually realize he'll need more than numbers being shifted to get him in a good spot.
Zed is cancer and needs a nurf. Not only does being AD base make his farming easy. He also has range, passive to more easily last him, hyper mobility with great escape from ganks and turret dives, and now this 
. All that and now you give him an item made just for champs like him that rely on quick diving burst. My only conclusion to this is the entertainment wow factor Zed brings to the big stage with dives, ganks, and escapes. When ever you see him in a pro games he starts to show up in solo even more because people think they are faker or some shit. Then they go full cancer and roam and escape, but not before the throw up their mastery shield and laugh. I'm over Zed. But they won't change him. He's like the poster child they want to have a reality show based on to make more money.
Basically every early game focused champion sucks to play against. Your objective on everything else is:
And Zed is quite possibly the nastiest of them. With tower diving and roaming power galore.
It's almost like they wanted to do something with the qss change.
I think you're mixing up cause/effect.
His ban rate rose after his win rate was above 50%.
