psa the 3 champs needing permaban are
cancer in its purist form and noone wants him on your team
needs nerfin
free tower dives

the only one of this list that has been an issue is irelia
yasuo and akali statistically suck ass
akali being only better then azir and ryze to give some perspective
I still don't get why everyone thinks Yasuo is so good. He's been in the gutter for like 3 seasons now receiving either very small in-direct buffs or complete nerfs. Especially with champions like Irelia, Akali (which you stated) and Jax coming back into meta again. It only gets more difficult for him to even be viable.
Yasuo, poke him down.
Irelia, yeah is strong, just don't let her scale too much and ask you jg for ganks.
Akali, when she shrouds just get away from it. That's it. Even if you're under tower. Get away.
