Yasuo loses to the majority of bruisers at almost every stage of the game
Azir lost to nobody and had burst-poke on a negligible cooldown followed up with absurd DPS and a 5 second wall that on top of being some of the best disengage on its own and preventing mobility past it, basically invalidated any melee for entire teamfights because they couldn't get around it, in addition to the fact he can WQE right behind you and ult you into his own team with no counterplay possible on your part. Let's not forget he also got attack speed for building CDR so he had even more gold efficiency than Yasuo with just a Nashor's tooth, on top of his free turret passive, on top of him having a knockup on his E that also gave him a shield, and the fact that he was more mobile than Yasuo because he didn't need minion waves. Oh, and his W does extra bonus damage to turrets; because him being a teamfight god wasn't good enough, he needed to have an extra nuke to towers. He's a lane bully vs almost everyone who also had one of the most powerful late games in existence.
but yeah let's cry about Yasuo because you're getting outplayed
