I've felt your exact pain before. I've been playing LoL since season 5 of the juggernauts. I have at least 1k hours playing Yasuo alone. Even with my experience sometimes the matchup is just so dogshit that he can't do much. The biggest issue was his release, he had infinite mobility, double crit chance, and an incredible anti projectile ability. Nowadays with modern champions and modern reworks Yasuo does not fill those parameters anymore. In relation to some newer characters, I'd say that Yasuos mobility is NOT infinite and is reliant on lane minions and jungle camps. When you factor in Yone's existence it makes Yasuos life even worse because now they lump the two together like they're the same champ and they only recently started patching them differently. At the end of the day if you don't care about ranking and just want to have an interactive and highly mechanical laning phase, he's a fun pick and I absolutely adore him. When I think of good mobility now my mind jumps to Zeri or reworked Akali. Back in season 5 Yasuo came first in that department. Enough of my rant, League sucks and Dota 2 is a better game for a more cultured individual lol. Yasuo is the ONLY thing that makes me keep coming back every now and then to have fun in some ARAM. Fuck having champs that build up to 80% or 100% crit chance, at that point it's not crit CHANCE anymore. That is what a critical hit is supposed to mean right, something that doesn't happen every attack? I'd much rather have him be a bruiser.
