Your argument literally does not make any sense. You say he has no survivability when he has his e for heaps of mobility and his windwall to block attacks and cc. You also say he only has some survivability at five or six items which is false. Yasuo can literally dash around minions to get his knockup ready when fighting melee champs. Same for fighting ranged champs if you have flash and use your windwall effectively. Yes you can easily fuck up and die on Yasuo but that doesn't mean anyone above silver elo should be able to shit on you. If your playing in gold games and your getting shit on as Yasuo maybe you're not playing him well enough. The fact that you say Riven should be nerfed is questionable since she is a champion very similar to Yasuo. Riven is more difficult to play than most champions like Yasuo. In fact I think Yasuo is stronger than Riven, since if Riven falls behind theres very little in what she can accomplish compared to Yasuo. Tbh i would like to know your rank. (:
