Akali rework idea

With the assassins rework coming and the fact that akali is likely to be reworked, I have some ideas that could be interesting.

• Her shroud could make her untargettable by auto attacks and targeted abilities, but not by skillshots or AoE attacks. She wouldn't be entirely invisible, but kind of like when a champion is revealed by the red trinket (with better visuals, see gif i made from this video (around 5:45)
• her old ult could be set to her new E, since her actual E is not that awesome as an ability, but with the following changes : It wouldn't do damage, but it woul proc her Q's mark. (still dash and still 3 charges replenishing over time)
• her passive and ult would be new, and her Q would remain practically the same.

I know it's not complete but the shroud Idea I find very interesting, mainly the reason for this post, as it allows her to buy some time while not being entirely countered to the point of making the ability (almost) useless just by placing a pink ward.
