How to fix Vayne: Buff her true damage (hear me out)
Look, a lot of people hate Vayne. It has become the "cool" thing to do. But the problem isn't Vayne, it is her build. She builds for her Q, as her true damage is shit now. If they buffed her true damage, she wouldn't have to level Q until late game. This would give her the buff she so desperately needs without making her toxic to play against.
