As some of you probably noticed in the last 2 champion spotlights (that being Sejuani's and Trundle's remake) every time a champion is effected by a crowd control effect, there seems to be a white bar that appears underneath the mana bar, which I think indicates the duration of the CC effect. Now that's just my theory since I don't know for sure what exactly it is.
So I would like to ask you ladies and gents... does anyone has any official info on those bars or are we just gonna look at them in patch previews and Champion spotlights? Any info is appreciated regardless if it is official or not, theories are also welcomed.
PS. Grammar nazis are not appreciated and I have the excuse of English language being not my mother language.
