Main Problem With Yasuo

I really hate yasuo . His design is really bad and player's that play him are toxic as well. Just look at his abilities. He has no mana and he gets a shield for fuc*ing WALKING AROUND. His abilities have a small cooldown so he can spam his q which deals a lot And the most annoying thing is his shield. Back in the day I mained Braum . Braum was design to have a shield and that is his main weapon. I know he can move it, but it can't block global ults or longshot abilities. It just blocks the damage. However yasuo just makes a huge shield and the global ults like jinx's or ezreal's just DISSAPPEAR like nothing. Even Ornn's ult. Why does yasuo have a much better shield that a champion who was made to mainly have a shield. That just makes no sense
