Some champions are outrageously squishy...
Yasuo.
I feel like he deserves more health since he's a fighter, not an assassin.

Average HPs is ~500 @1 and ~2000 @18, where Yasou has 518 and 1920, which is extremely average.
Also, it's worth noting Fighters, or Tanky DPS, tend to fall in 2 main camps regarding how you build them.
Camp 1 gives you free DPS so you build straight tank and then have DPS and Tank.
Camp 2 gives you free tankyness so you build DPS and then you're tanky DPS.
100% evasion, invulnerability, spell-shields, clones, invisibility, untargetability, invulnerability and immunity to CC - there are plenty of solid mechanics light fighters have to be effective.

And block the damage and CC of those ultimate not for just himself, but his entire team.Yasou arguably has the single best 100% damage-block skill in the game through Wind Wall.
My advice would just be reading up on Yasou guides or practicing more with him so you know exactly when to use his defensive skills and in what scenarios Yasou's defensive skills allow him to function. He's extremely durable with a glass build in the right hands or in the right scenarios.
yasuo is a melee adc or "light fighter". his entire thing is being squishy in melee and dealing a ton of sustained damage.
for being squishy, they gave him plently tools to outplay hios opponent and play around the fact that he doesnt build defense. he requires a large amount of mechanical skill and micromanagement. but played properly, he can carry the shit out of a game.
