Mirage in ranked

@PholanxTTVI play mirage occasionally in regular games. I agree he is not viable in higher tier ranked. Its always the same 3 or 4 legends (you can guess who).
I would like to see mirage's passive be permanent. When he is downed, he stays invisible. Not game breaking, just makes him harder to "thirst".
A change to his decoys: have them mirror player movement. I jump, they jump, etc. Straight line decoys are only shot by inexperienced players.
If they both have "normal" movements, I will be 50/50 which one to shoot.
Such a change would require increasing the time to get decoys, as they would be much more useful.
