Jax's winrate went up 1.2% with those buffs
Which is actually a huge change. That's fine, I didn't consider Jax necessarily weak before that buff but I also think the current meta of top lane is shifting towards his playstyle in both itemization and playstyle. All I know is that he better not get nerfed because Riven was literally made to be brainless to play and her w/r went up without nerfs, so Jax better get the same treatment.
