Illaoi Changes

I feel that Illaoi has to be one of the most satisfying yet underwhelming champions in the game. She has these incredibly high moments, but they occur so infrequently that it is never worth playing the champion. She has a clear identity, high damage dealer with no crowd control, but that lack of any crowd control and virtually no gap closer makes it incredibly difficult to play as her. If she could have a little bit more utility that would allow her more consistency, I think she would actually fall into a healthy spot, potentially a niche pick in competitive play even. I had the idea of Illaoi getting a slightly scaling slow passive on her tentacles (Passive, Q, and R) every time she placed a point into her ultimate at 6/11/16 (30/35/40)to help her really feel like her zones have a meaning to them. Especially late game, it feels like hitting tentacles has not that much reward for how difficult it is to land them consistently. If players somehow stumble into Illaoi's zone, they should be more properly punished, especially if they lack mobility. Currently people without hard mobility can simply walk out of Illaoi's ult zone as zone as she tries to go for it and Illaoi sits there feeling useless. With this added soft crowd control, I feel Illaoi will actually be able to scale in the game, and be more useful than just a short lived lane bully. Thoughts?
