Shen Q Change

Shen's Q (the thingy that pulls his blade to him and gives him increased magic dmg for 3 attacks, and even more magic dmg for 3 attacks along with increased attack speed if it goes through an enemy; who of which is slowed when moving away from shen for 2 sec) is a lil annoying sometimes when I pull it towards me, because sometimes I'm not sure if the targets it went through get marked. I feel a mark or something should visually appear around the target to inform the player of who all it hit.

EDIT: Oh also a sound or something should be heard as well when it goes through an enemy.
