How long is riot going to let Galio sit at a 65% winrate before they do something about him?

Seriously! He's literally making twisted treeline unplayable! He has a 65% percent winrate! That's just not fair! Honestly, I hope riot can crack down on this, i'm tired of riot playing favorites and constantly making galio the strongest champion in the game.

Oh yeah, he also has a 100% winrate in brazil. Please riot shill snowflakes, tell me he's balanced.
