Why is the hardest champ in the game also the second weakest?

Talking about yasuo o, the undisputed god of high skillcap. Why would Riot create a champion that is arguably the hardest in the entire MOBA genre and then give us absolutely no reason at all to play him?

If you actually have the incredible amount of skill, game knowledge and mechanics that is required to play him you will get punished for it, no matter how fed you are you will never be of any use, it's as if dying to yasuo is the same as getting executed by a turret.

The only way he can be viable again is to increase the e distance to 450 and increase his Q scaling to +120% total AD (non-isolated), +250% total AD (crit) and give it full on hit effects to all targets hit Might not be enough to compensate for all the nerfs but it's a step in the right direction.
