This is why Yasuo is unfun to play against...
Now before you tell me that I don't get Yasuo, or I haven't played him, let me explain something. I was playing him the other day to "understand" where Yas players are coming from when they try to defend their champion.
I learned some things from that game:
-I do at least understand how some players would definitely find yasuo fun, but... -His scalings are insane -I did terribly in lane, I died four times and was behind in CS. By 20 minutes onward I was still doing insane amounts of damage. -Players don't appear to be rewarded very well for shutting Yasuo down in lane. He scales so well that shutting him down early means almost nothing.
This is consistent with many of the games of which I've played against a Yasuo as well. This is why Yasuo is shit on by the community because no matter what people seem to do he can still end up dictating fights dealing damage and getting triples or more out of his ass.
I do admit I am mechanically a very bad Yasuo, but even then I was simply spamming my Q and E, shredding through their team and blocking projectiles with ease because of the way my windwall spawns.
Please do something about his scalings or windwall I actually beg.
