Can someone name one patch since yasuo was released where he wasn't op?

This patch since the warlord+Shiv nerf.

He recently became powerful because of the crit mastery and how much easier it is now to obtain 50% crit through 2 items.

In between the nerf he was released and now, he was considered " unlucky " because almost everyone loses with a Yasuo on their team.

Also, is this an honest speculation? or are you just salty lmfao.

the majority of any patch that took place during spring of patch 5, didn't become "reliable" again till they fixed his Q cooldowns and his shield. For a long time his shield wasn't even noticeable. Then he only became "amazing" again during early season six to be nerfed into being "good" at most recent set of patches. Hell even late season 4 he was really bad and had a super low win loss ratio globally.

as another person mentioned, his release date he wasn't that good

I would like to add though that all the champions he renders useless in a fight now had much higher damage values previously

Between patch 4.18 and patch 4.21 he was basically free kills.
