I now understand why Yasuo has such a high playrate in ranked
Note that I am not advocating the playing of Yasuo, although I do think he is unbalanced
The amount of snowballing and feeding in this game is un believably high, that solo queue players feel helpless to win games. A good point of some Yasuo players actually gives them a reasonable chance to win games by themselves even if teammates feed.
Although this isn't really a Yas problem, it's a matchmaking problem.
Just thought I'd share.
