Every single champion in order of skillcap

Upvote and comment for visibility if you find this useful. I define "skillcap" as the difference between the win ratios of the least experienced players V.S. the most experienced players. Statistics pulled from Champion.gg and analyzed for most played role only. Some statistics ended up negative (1-5 games played had a higher win ratio than 125+ games played). For those, I put 0. All numbers are in context of percentages.

I found this extremely interesting to compile. It's interesting to note how champions most often considered OP are ones that have relatively low skillcaps with high base win ratios. Hope this is useful to someone. If anyone has any better ideas on how to format this beast, let me know.

*EDIT: This isn't personal opionion, this is_ literally just the difference between win rates of 0-5 games and 125+ games_ Check my math if you dont believe it.
