Vayne Rework Idea [Top Of Head Post]

[Q] - Vayne rolls a fixed 350D towards the cursor, increasing her next Basic Attack's damage by 10/25/40/55/70 (+30% Bonus AD). With Final Hour active, Vayne is Stealthed for 0.5/0.6/0.7/0.8/0.9s on cast. <Mana> 35/40/45/50/55 <CD> 6

[W] - Vayne's basic attacks permanently inflict 0.4/0.5/0.6/0.7/0.8% of the target's Max HP in bonus physical damage. Basic attacks on enemy Champions also mark them with one stack of Silver Poison per hit, while every third hit consumes all stacks to inflict 15/30/45/60/75 (+10/15/20/25/30% AD) bonus True Damage. With Final Hour active, this physical damage bonus is doubled.

[E] - Vayne fires a large crossbow bolt at the target after a 0.5s delay, inflicting 40/70/100/130/160 (+45% Bonus AD) physical damage and knocking them back 600D. If the target is knocked into terrain, they take 100% additional damage and are Stunned for 0.75/0.9/1.05/1.2/1.35s. With Final Hour active, this knockback is increased to 775D. <Mana> 60/65/70/75/80 <CD> 13

[R] - Vayne passively recieves 25/30/35% bonus Attack Speed while targeting an enemy Champion. On cast, this passive is doubled for the next 8s and Vayne also has a 250% increased Ability Movement boost, as well as bonus effects on her spells. <Mana> 100 <CD> 130/115/100

Ability "Night Hunter" - Vayne recieves 30 flat Movement while moving towards any enemy Champion within 800/850/900/950/1000D. This does not apply to Champions that Vayne cannot see.

I did the math and modifications to everything, and I feel this is a much fairer build for Vayne that doesn't take much away from her mid/late game powerhouse identity. Hope you enjoy it
