From teh PBE today
You and Me (W) "Enemies now gain an assist on Yuumi when damaging her attached ally. This will prevent things like execute while safely attached." "Dash is now interrupted by ANY immobilizing CC (Same as Yasuo E now)" Adaptive share changed from [5/9/13/17/21%] to [5/7/9/11/13 (+4/7/1013/16%)]
Um Tell that to 
's E and Yasuo's E
The Ecdysiast1 votesUrgot's E isn't supposed to be interrupted, because it's a very short engage tool that also can't get over walls.
5050BS1 votesYou dont understand. When Urgot Es at Yasuo he can just press E and go right through Urgot and NOT get stunned and takes no damage.
So when they say "Dash is now interrupted by ANY immobilizing CC (Same as Yasuo E now)" They are lying.
