people walking out of amumu ulti aoe stun

next time this happens, ill grab a video snippet of this.

keep forgetting to.

but since 9.3 patch. ive had 5 times now (over 2 games. 4 in 1 game and 1 in a second game)

where as amumu. i VERY CLEARLY landed my ulti AOE root/stun on an enemy (without them having ANY temamates near by, no QSS, no cleanse, no tenacity runes, no tenacity items) only to have them walk right out of it.

by very clearly. i mean VERY CLEARLY. like not with them on the very edge of the circle. but clearly within it. as in closer to the middle than the edge. each of the 5 times this has happened i've been in a voice duo, and my duo partner saw it as well. and we were both like "WTF?"

i say this has happened 5 times. because there are 5 times that i VERY CLEARLY landed it, and had time after to check gear/runes/etc to 100% know there was no way for them to have avoided the stun. theres many more times this has happened since 9.3, but due to circumstances (middle of team fight chaos or something), im not sure. they might of had an ability (dash or something) that was simultaneously cast to legitimately get them out.

like i said. next time i have this clearly happen, ill try and make the effort to grab a vid of it.

but just wanted to know if anyone else has noticed this happening?
