Ekko Suggestion

So I was thinking.. (It might be OP but its just a suggestion) While playing Ekko maybe there should be some kind of colour indicator on his Ultimate icon to show when his Illusion is near the enemy and. For example in team fights sometimes you cant see where exactly your Illusion is, and maybe this indicator would help people hit their ultimate better. For example when noone is around the Illusion Ulti could glow blue and when someone is around it could glow red, so at least 1 enemy is hit.
