Vayne has the highest win rate among ADCs, jumping from 51.22% to 53.19% according to champion.gg. For most League players, this is a problem.
We are talking about whether we should make changes to Vayne in 6.24 (the patch we're working on now), given she does look pretty strong. Twitch isn't currently on our radar, though possible that could change. Other stuff we'll likely be looking at includes Courage of the Colossus, Fervor, overall increase in magic damage from Aegis removal, Syndra, Fiddlesticks and more.
We’ve strayed far from the path of the retro Blade of the Ruined King build on Vayne. Now it’s all about building that critical strike that is obliterating anything in her path. Paired with her ultimate ability, Final Hour, which buffs her AD, movement speed and grants her a second of stealth when she uses Tumble, she is a champion to be feared.
Before, Vayne had a hard time matching up against Lucian, Jhin and other ADCs that used the Youmuu’s Ghostblade or Duskblade of Draktharr. Now that those items are pretty much limited to assassin’s usage only, she has risen to the top of the ladder.
Courage of the Colossus has also been a huge problem on crowd controlling tanks, giving them giant shields for one-on-one skirmishes or team fights. Tanks that never had particularly high win rates have shot to the top of the list of dominating champions this patch. It was slightly concerning that the mastery wasn’t being nerfed on the PBE’s current cycle, but we’ve been assured that a nerf is incoming.
That being said, now is the time to get in your Vayne games and tank games now if you’re trying to climb in Flex Queue. You guys have two patches. Get to it.
