I don't think i've ever seen such discrepancy with winrates
For all the years i've been playing, most of the time champions' winrate would be within 47-53%, with a vast majority being between 48%-52%, and a few oddballs above or below.
But lately, winrates range from 44% to 55% on so many champions. I don't think i've ever seen the meta enforced so much upon the game before.
Sure, winrate doesn't mean everything, which is why champions like Ryze has been sitting at a low winrate for such a long time. I still think it's disgusting to know that champion selections means so much now, with some picks being far outclassed by others.
