... so i've been playing malzahar the last couple of matches and i've notcied when i ult a high mobility champ like 
or 
(yi's ult doesn't prevent roots or suppressions)that it will root them for a split second then they will move and be rooted again all while still being ulted by me :| anyone have any ideas as to why? i'd like to get a red to look at this as well :|
It's probably a bug, not so much being broken. I've seen that happen too, but as long as they are dying, I'm okay with it. Now, if they were able to freely move while I'm ulting, I don't know how I feel about that.
a little side note: i feel as if they are spam clicking away from me as every time they move its in a way that would be logical of them trying to escape (e.g. nearest bush, into the river, jungle, toward their team, ect)
that happened to me as well it was even in a ranked team battle
Huh, it seems that there is a counter to mobility creep!
Besides, you know...
and 
and some others, as well as Malz only being able to ult one person.
