Nerf Vayne

I started a game playing Yasuo top. I am against a Vayne. Level 1, her auto attack does 50 attack damage, her passive does over 200 attack damage, and her Q does over half of my health. 5 minutes in, she is 4 kills and 0 deaths. She is actually overpowered. Please nerf her. This is going out to the public. If this keeps going on, no one will play your game anymore. Unless all you want is money. This is for the good of the whole entire game and your players.
