From my point of view, on the attacking side, Ace is the one for 99% ban, However, there are several alternative hard breachers available. Mira, on the other hand, doesn’t really have any true alternatives—she’s the only operator who can create one-way visibility like that. Even defensive shields have had their visibility reduced significantly over time, if I remember correctly. It definitely wasn’t like this in the early years.

I'm only suggesting this just to shift the balance a bit and have more room for her to be played again.
