Vayne Rework

Before anyone loses their stuff, especially Vayne mains, I'm not advocating a total rework, but rather a small something that will alleviate her problems while enhancing her strengths.

She is the de facto tank killer, taking away a percentage of her target's health in true damage. This is such a powerful defining feature that it's basically central to her identity, but the way it's currently implemented causes her to be limited.

It's part of a three hit passive on her W. Since it is so powerful, Riot has to nerf it, so that it is only on one target at a time. I cannot accept this because it makes Vayne such a niche pick in draft.

So I thought of a workaround, so that it doesn't apply after three hits automatically. Instead, the proc should occur with activation of her Q and auto.

This means that she can build Runaans Hurricane for the extra waveclear she so desperately needs, and the W passive applies the three stacks to ALL targets hit, but it does NOT proc the passive true damage effect. Instead, the true damage procs with her Q and auto on a single target.

This allows her to apply her passive to the entire enemy team during a fight, and then Q, and then choose her next auto attack on an enemy to proc the W passive for some massive true damage burst.

This would allow greater build variation with Vayne while keeping her three hit true damage burst, and still be a tank killer.

Balance changes may have to occur, such as damage reduction on her Q, but also an increase on her W, giving her even more burst potential on a target. But we can let Riot figure out the numbers on play testing.

I'm just trying to think of a way to allow Vayne some better item build variation, but still keep her W passive viable. What do you guys think?
