"A high skill cap champion shouldnt have 45% or higher winrate"

I saw this in a vayne post recently (dont get me wrong i actually hate vayne unlike most champions i defend) but i saw a post on how high skill cap champions shouldnt have a 45-50% winrate. I disagree.

I think what the league community thinks high skill cap is, is that you need 75 or more games to break 50% winrate. While high skill cap champions should be hard to play they still should have a balanced winrate. What that means is that MOST people that have few games on that champion still lose, and MOST people who are good at that champion still win.

A lone winrate doesnt determine the amount of people who have high number of games on them. So i ask you stop basing nerfs on "well they have negative winrate but they are high skill." They way you balance these champions is making them take more skill. But not to a point where learning them is so much a challenge that its not even worth it

HOWEVER: I couldnt find updated Data on 6.24 for vayne so i cannot say wether or not she is still a problem. But as for the people upset she still has a 2 item powerspike. Its called a powerspike, so until I either fight a vayne (which i havent yet this patch) and judge if shes still a problemm (if i feed her to make her strong that doesnt means shes broken) or i find my statistics (champion.gg is updating in 3 days) i will not comment on her balance situation
