Can't believe riot never noticed that absurd broken bug (try it out if you don't believe me)

Is it intended or something?

edit: seems like riot made fizz ult stick on people even if you cleanse with QSS and other stuff at patch 6.10 it's dumb because QSS is supposed to be the ultimate anti CC

can't remove fizz ult with anymore? https://www.youtube.com/watch?v=g2oImOlV9Jk
