@Riot I'm okay with Akali being very strong assassin, but her Smoke Cloud needs to have counterplay.
She can spam abilities in her smoke cloud, auto attack you endlessly, and before you have a chance to get in some return damage she disappears into the cloud. I'm fine with her being able to invis even under turrets, but give me a fucking chance to do some damage back and punish her aggressiveness.
Literally the only option at this point is to run away, and hope you kill her before her 8.5 second shroud is back off cooldown.
