Vayne still sucks
Literally all the buffs did was make her "playable" in top lane.
Does absolutely nothing to Caitlyn Sivir or Jinx.
The only way Vayne "is okay" is when the support is literally boosting the Vayne. Does Vayne "really" carry games? Nope, just kill steals everyone and 100% baits, not a single ability to self peel.
Vayne playing from behind - can she even take the bot tower while the rest of the team is 4v5? Absolutely no waveclear potential.
