So I just played Sion into Lee Sin.
And he ulted me right after I landed my ult. Like the very second it landed, I was knocked back.
Uh...what the fuck? Sion is immune to CC when he ults, and Lee was definitely hit by my ult. So why the hell was I knocked back by Lee Sin's ult, when I hit him with my ult?
Can someone care to explain this? Or is Lee Sin's ult have some bugs?
