Sion's Ulti Bug
So I was playing a match today when I noticed the enemy sion's was moving really well in his ulti. I thought i was seeing things but then he did a 360 around our team before slamming into us. i think Riot's already been dealing with this but I think its safe to say that the sion was using a bug or script to gain such free access while in the ulti. Even his own team noticed this.
