Can Illaoi have a break CC on her ultimate?

This thread perfectly summarizes what illaoi needs right now http://boards.na.leagueoflegends.com/en/c/gameplay-balance/Ysgoczbv-for-illaoi-my-love

But I still want to go on what might be a slight quality of life improvement at least. My thoughts behind this has always been, I got to the center of their team and ult. It always depends on the matchups as well. The enemy team is rewarded by CC'ing illaoi so she doesn't dps the team into shreds so that's fair. What's impossible is when you either don't have QSS or treads and you get chained down and you can't ult to survive with tentacles.

Her power is a servant to the tentacles, without tentacles she is but a vessel and not being able to summon them when it counts, kills what she is about.

OF course her ult channel is unstoppable but it has a windup time that most people can just flash away from and if you don't have any items to keep you alive during the channel, those seconds matter a lot She has 0 escapes and she is easily kited, She has no movement speed buffs outside of items

Aside from flash ulting as the best way to engage a fight, she is really dependent on positioning and hard engage. Her playstyle revolves around cheesing her opponent for getting cocky, but since league is sapping the fun out of solo carrying and winning the game gearing around team fights, it would be nice to see a slight buff. She carries an idol of a god, maybe in a sense she could break through mortal chains to unleash the test of spirit in a sense.

Tl;dr CC removal ult, cuz teamfights get rough if can't ult.
