It shouldn't have been hard. Revert the health nerfs and the shield nerfs to Yasuo and
make it so that his windwall can't block anything until it's fully out or more specifically, have more of a delay before it blocks anything. It's bullshit how he can block projectiles with a Windwall that's still coming out. It would fix a lot of frustrating "bullshit" scenarios. It's just unhealthy how it can do that.
