I had (literally) a dream about a way to rework Yasuo :D
In my dream today. :D For real, in my dream I saw an upcoming Yasuo rework. Passive shield remained the same, but the whole kit was based on the flow system/management. So there was things like if you used Q with max flew, instant tornado, E-s CD was lower with maximum flow but higher the more you missed. I do remember there was something with wall, maybe it only functioned above 75% of the flow. Ult remained the same. I do not know what could happen with the bonus crit chance. So ye, basically, maybe it seems a better idea in my mind then here, but hey. :D I just wanted to share you my...errr...thoughts? :D
Anyway, I think that is a way where Yasuo could be still viable (like if you ult, max flow so you find yourself in the middle of the trouble but you can use wind wall effectively), but at least people would have windows to punish him. I find that a good way to start on for RIOT, if you have any thoughts just discuss it guys. ^^
See ya,
