I'm not really seeing the reasoning behind the shroud changes in the patch notes
On the subject of making her more unique, we’re playing up Akali's 'smoke bomb' to feel like a more potent defensive tool, giving her more ninja-like ways to juke, dodge, and mindgame her opponents in combat.
Akali's shroud is already very unique to begin with and it already does a great job of giving her ninja-like ways to juke, dodge, and mindgame her opponents. Is it really necessary to try to add more uniqueness to something that's already very unique to begin with? I would argue that it makes the ability less unique because the blink turns it into a generic mobility spell used to move around rather than a strategic smoke bomb used to trick your opponents. She already has her ult as part of her ninja-like juking so why take away the uniqueness of an ability to give her something she already has?
