Remember when you could at least bully vayne early lane?
Say goodbye to that now, because instead of at least "kinda" committing to get her silver bolts proc'd now all she has to do is auto attack, and Q which is an auto attack reset and BOOM she won the trade in about a second with no way to fight back because it's also a gap closer/gap maker aswell. Dont forget them buffing her silver bolts aswell, making them stronger mid-late game. And dont worry, if she gets late game she heals for 20% of her target's maximum health on their death during ult .... ON A TANK BUSTER CHAMPION.
Seriously, i usualy say wait until people test it, but this just doesnt seem logical, vayne isnt weak, vayne is fine - she has her niche and people who know how to play her know how to play around her weaknesses and improve on her strength's, she has too much power to also be a general pick.
