I love using Mirage but he seriously needs a buff. What's the point of him turning invisible when you can honestly still see him.
If you can still spot him then he should still be able to still have his weapon or at least have an option to end his ultimate. If that can't happen then at least make his decoys move not just stand there. Third option would be to simply make him more invisible, harder to spot. Those are realistic buffs yall can seriously work on. Nuff said!
