If you could remove a single Champion from the game, which one would it be and why?

There's just too many champions in this game I feel like they're just adding them now just to milk the game more. They added 10 bans to the game but even that's not enough. I feel like there's too many champions to ban that actually are just more OP than other champions. I guess if I had to remove a single champion from the game it would be Kayn. I don't agree with him being able to travel through walls and gain HP that just seems so broken too me.
