The rework vayne deserves.

So heres what im thinking, vayne is currently a no-counter-play monster because of her obnoxious kit (yes im a bit butthurt, sue me), She has loads of self peel with her E, super low cooldown on her Q making her untouchable and excuse me, but true damage as precent of max health damage is pure bullshit, also her passive makes her impossible to escape, so you cant catch her and you cant escape from her, the only way to counter her is to fight her 3v1 (at least) which means they can 4v2 or take objectives freely just because you want to kill her... so heres what im thinking, a rework suggestion that wont gut her, but will definitelly give her a niche (which riot wants) and leave her viable.

Passive (new): Vayne cant deal critical damage, instead her crits deal true damage instead of physical damage. (This gives her much less damage than other ADC but it crushes tanks and gives her loads of late game power.)

Q (changed): Vayne now turns invisible whenever she tumbles (not only during ult) but has a longer cooldown (3.5 seconds at max rank after the bolt is fired, instead of 2) and the shot always crits.

W (new): vayne passivally gains 30 movement speed when moving towards enemy champions. when activated this effect doubles.

E (nerfed): Works the same but impaling the enemy stuns of 0.5 seconds down from 1.5 seconds. OR snares them for 1.5 seconds instead of stunning. (Am I the only one that thinks that a 1.5 second stun on an ADC is crazy? even assasssins dont have this kind of CC.) also, the damage deals 5/5.5/6/6.5/7% of the targets max health in physical damage, can crit for true damage. remember that this can happen twice, dealing a total of 14% of the targets health in true damage. (maybe lower the throw distance by like 50-75 units)

R (New): Gives vayne a 100% crit chance, lowers tumbles cooldown by 1 second, automatically activates W for the duration of the ability and she gains 30/40/50 AD for 12/13.5/15 seconds.

Id love to hear your opinions, I think this is balanced but Im not perfect, So I might be wrong. This is also my first discussion, so sorry if I messed something up and Im not a native english speaker, so I apologize for any mistakes in my english.
