Shaco is totally useless within the inner turret [GAMEPLAY]

Shaco becomes totally useless when he gets the shield buff from the inner turret. If he ult's only he will be shielded not his double, which is a huge give away for which one is the actual Shaco. I also noticed that when you use his Q which makes him go invisible the shield still remains visible, which is a huge give away to were he is located. Please fix this riot its really going to kill the viability with this champ.
