Make it so Cassie´s E doesn´t proc the 1.5 second slow with Rylais
It´s kinda stupid that a champion can literally perma slow you , due to the fact that Rylais will apply a 1.5 second 40 % slow on a ability that has a 0.75 second cd. And since giving her E a 1.5 second cooldown would gut her , make it so that it lasts 0.5 seconds , and is a 30% slow , so that way she has to land her Q to get the movespeed to keep up her E damage to kill her opponents.
