Akali and Yasuo solution - please meddler and scruffy
I know everyone has an opinion on how to nerf/buff a champ and I know it's a very very complicated job.
Please read my simple idea, many already mentioned but it seems to get ignored.
Yasuo - remove his passive shield. There was a recent thread by scruffy about overloaded kits, I have no idea why yasuo isn't a prime example of that?! He is one of the most banned champ for reason. He already has a very impactful defensive ability with his windwall, he shouldnt also have a passive shield. His waver clear is one of the best in the game. He averages one of the highest cs for a midlaner, and thats because his shield. Make him work for his cs like the rest of us. If removing this shield makes him a little weak then buff damage, atleast he will no longer have an overloaded kit.
Akali - shroud should be 2 secs in duration and disappears after she comes out. The shroud should give her 2 options, either to escape or to rengage, NOT to go in and out for eternity. I don't even mind turrets not damaging her when she is in the shroud, atleast my counter is to wait 2 secs or know once she comes out she can't go back in. She is frustrating to play against which I'm sure everyone player knows. If she has low win rate then buff her damage or something, but remove this overloaded unfair ability.
No excuse me while I go pray in hopes Meddler and Scruffy listen.
