Riot, did you remeber when yasuo was less problematic?
For me Yasuo was less problematic when He didn't restore his shield after ult, this forced Yasuo to chose the right way and the right moment to go in. You could also keep nice mechanics as the passive w, that was removed. This will make also his windwall more important in his kit and not only an ability that makes his kit overloded. Yasuo has too many skills to protect himself for an hypercarry who has his powespikes after statick( passive shield, windwall, shield after ult). This is just a my opinion
