How to fix Akali's shroud.
It already seems like it kind of does this, at least visually anyway, so it shouldn't be too hard to pull off. Make it so her shroud slowly expands over time like it currently does, but it would develop patches where people can see her in. And the longer it's active the patches become more and more prevalent till it completely dissipates.
Now you get a little counter play, since you can sit in the patches and maybe see her long enough to actually get an auto off when she uses it. Cause atm, "waiting for the CD" doesn't work because good Akali's will just E away from you until their shroud is up anyway. Some form of counterplay is needed.
