The one Akali nerf that I would accept
Is that if Akali is hard CC'd in her shroud she is completely revealed for the duration of the CC allowing you to target her. Anything else I think would make her literally non viable with her current kit. This would at least give a solid counter play to her shroud.
would become an insta counterpick. Imo, make W give a bit less energy, and reduce the max duration by maybe 1-1.5 seconds
