CAST-OFF SKIN FOR CASS. New passive: Ninja scroll treatment.

If anyone has seen "Ninja Scroll" you know what I am talking about. There is a snake girl called Benisato. When she needs to escape she leaves a shell of herself behind to be targeted by foes. Cass could do this and stealth for a certain amount of seconds on a cooldown. Then they could put her stacks passive on an ability and give her some slight escape that is in line with her theme. She would still have her stacks but now she would be viable.... well more viable. Now they just need to tweak her to bring the pain. RIOT did it to themselves though. it must be hard to balance what is in effect an ADC mage.

Stand toe to toe with her and get melted. They nerf her down and now you don't have to run. I'm bronze and I USED to burn people down even when I went support with her.

Oh and the cast-off skin can be ulted because it doesn't change color and crumble for 2.5 seconds or so like half the length of what her stealth would be. True vision exposes her as normal. Thoughts?
