What they shouldve done with Vayne.
Back in preseason, Vayne as changed and called the "tank shredder marksman", mainly because of her W, Silver bolts.
However, when riot decided to buff her, they buffed her Q. I was so weirded out by this. Her Q is a burst ability with movement, since it increases the damage which scales with AD. Thats why it became much more efficient to rush B.F rather than go for Cutlass like we used to.
This buff completely contradicts the "tank shredder" thing since this kind of damage is the one tanks resist the most. They shouldve buffed her W, not her Q, never her Q if they wish to fulfill that shredder thing they established back in early 2016.
The buff to her Q is what allows her to burst so much, with the added damage of Statikk shiv. And as far as the posts go, I think that is the main concern of most people. Vayne is my most played champion, and i dont like her how she is now. I want that attack speed reliant champion who would deal consistent damage and was actually hard to play. Right now its just position well (which all ADCs must do) and just Q and deal a shit ton of damage, its not fun anymore. At least in my perspective, and most enemies perspectives.
