Do something about Vayne

Delete her, make her autos do zero dmg, take away invisibility, get rid of her stun. I don't give a fuck what you do but make this champion not an auto win just for existing in the game, which with how disgusting that champion is right now (since you decided to give her perma invisibility after deleting all counterplay to invisibility) is all she needs to do to win the game. Pick Vayne and if you have a 1/20th of one brain cell good job you win.
