Yasuo needs a redesign on his damage scaling.

The last game I played was 4v5, and the Yasuo still easily became a one-man army on the short-handed team.

If the Yasuo knows how to play at all, it's a guaranteed victory. All he has to do is stall the game long enough for his damage to go through the roof. Add a guardian angel or a support champion to heal or shield him and he can pentakill the other team every fight. There is no CC that he can't just windwall. You can't outrun him. You can't build defense because his damage is just too high.

This champion has some interesting play style and abilities, but his late game damage is completely overpowered. The whole "double crit chance" thing is just broken and needs to change.
