Stop Banning Zed
There are champions that are difficult. And champions that are easy.
Some champions have bigger payoffs than others.
Annie + Veigar mains. You know what I'm saying.
(
main: OH MY GOD I GOT A TRIPLE KILL!)
(
Main: Kay, that's another quad.)
Zed overall has a 48% win rate. There are a ton of champions and items that shut him down,
Not to mention everything that has shielding abilties.
Also, he is an assassin. So these will do as well

You should really ban something OP so riot knows what to nerf. Or ban champions you specifically do bad against.
Here's a few ideas.
(Shields on Shields on Shields.)
(Free zhonya's every 8-13 seconds?)
(I mean. Pretty damn near constant twitch ult with built in stun options.)
