The point of Vayne and Kogmaw specifically is they are hyper carries. They are completely designed to win if the game is pushed to the point where they can each get all 6 items, whereas the other ADC's either burst early on (Like Draven) or do serious sustained damage all game (Like Ezreal and Corki).

The one thing i would say though is that removing any part of her kit would ruin her. I literally cannot imagine a Vayne without her stealth, true damage, speed boost... none of it works without the rest.
