Why do people think a 51% winrate isn't really strong?
Go back 3 or so years and people were begging for nerfs when champs went above 51% winrate and had more than like a 6% playrate. And those champs pretty often got nerfs.
So why is it now that only absurd playrates or 53%+ winrates are being called out?
Part of the issue with balance now is what's seen as out of line, both from the community's perspective and Riot's.
