Vayne really needs a rework
mid/late game vayne is really broken, the true damage she does is unreal and there's no way to build against it, short of hp, but given how much ad she can do, and how quickly she can unload+keep distance from her opponent, she melts insanely fast. I went hardcore tank in a recent game against a vayne and still got melted, along with my team in a split second. We were all pretty fed too, it was just a complete slaughter. I think certain champions being strong is a good thing, but vayne is way overboard.
