Lol so are we seriously trying to circlejerk vayne now?
As far as I know pretty much everyone has been saying she's balanced and has her glimmering weaknesses. Now people are just now starting to complain about her so they can have her nerfed after losing to a fed vayne. A champ who's designed to have one of the best late games out there while having a very weak early game.
when I see a Vayne on the opposite team because it's passive is really nice against her with the armor. I don't think she preforms as well currently because of items people are getting, and that she has to be so close to her enemies to do damage. She's not ineffective at all, but she definitely comes with some downsides.
