You can ban 4.31% of the champions in league, in ranked.
That means 4.31/100 dudes are BANNABLE. If you were to randomly do something with luck, and the chance of you to win was 4%, that means you'd win 4 times out of 139.
Just let all of this sink in. 4.31%. 4.31% FUCKING PERCENT.
And about 20% of the champions that exist are toxic/OP as fuck. Whatever, 6 bans anyways, I'll just ban 4.31% of the champions possible out of 139.
