When Riot thinks they're slick...

I still remember when Soraka dominated mid lane then Riot completely destroyed her to a point where she wasn't even playable anymore...then put her skins on discount.

2nd chance get in here we need you.

But Yasuo still gets banned 90% of the time.

there is such a place called "normal" games where bans do not take place...

play blood moon game mode, and pick yas first since there are no bans there.
