What happened to mirages decoy copying his revive animation?

What happened to Mirage's old decoy being able to mimic his review animation? I don't think there was ever an official patch that mentioned that this was removed. Please bring it back so that mirage can be more useful during a fight. There are so many support characters that can revive in the middle of a fight. Please bring back his decoy being able to perfectly mimic what he was doing so that he can live up to being the bamboozler.
