Master yi Q

After you use it he stops moving, so in a fast chase fight having master yi just dead stop after using his Q is a huge thing to those that play yi they get it, so like mid of a fight i use Q to damage and to dodge some hits but on kalista who keeps stick and move fighting I cant have Yi come to a dead stop like hes been stunned even though their was no stun or cc effect he just dead stops after he uses his Q.
