It's 2018, can we please finally address the Yasuo problem?

Everyone has encountered this problem repeatedly: in every single game, Yasuo either feeds or gets insanely fed. There is no middle ground. Whether it's a problem with players who gravitate towards Yasuo or the champion design, it needs to be fixed.

If the problem is Yasuo as a champion, his kit needs to be changed so he doesn't turn into a buffet for the enemy team once he's behind, or some sort of unstoppable force if the game lasts long enough. If the problem is with players who gravitate towards Yasuo just not being good at the game, his kit shouldn't be allowing them to climb without getting better.

Whatever it is, it's extremely unhealthy for the game, especially in ranked play.

i.e. in my last game, I had a Yasuo main with 70% win rate this season, laned against Darius. I counter-ganked for him and we got first blood, then he got ganked and died while I was doing dragon. From this point on, he was near instantly dying every time he entered lane, ending up something like 1-8-0 before he went to another lane.
