To everyone saying Vayne is OP and needs a nerf.
She isn't OP, other carries are UP. Other carries need buffs. She hasn't been touched in ages, and only recently is outperforming everyone. This is due to item changes, and stat changes ON OTHER CHAMPIONS. She has the exact same strengths and weaknesses she's always had. Stop crying for nerfs, and starts crying for buffs. I know all of the boards just love to cry for people to get nerfed, but in reality that won't fix this situation. Vayne has power because of her kit. She is VERY item reliant, because other than her 3rd hit with w, that's where all the damage comes from. Both of her AD scaling abilities are not spammable, and have long cool downs without doing much damage. One of which pushes them away, or into a wall. OTHER CARRIES have scaling abilities that have been progressively nerfed.
The fact that all of this has been ignored is why RIOT goes to reedit, and mostly ignores the boards. (except RiotRepertoire) The correct way to "nerf" Vayne is by buffing other carries.
