+1, character is cool as hell and deserves way more screen time than she got.
The redemption arc they put her on was really cool and refreshing to see since since seeing characters actually grapple with their past wrongdoings and struggle to improve themselves is a pretty rare sight, and it sucks to see that turned into a generic "and then she sacrifices herself to save the day" redemption story.
I also think that bringing her back could tie well into a general "fractal weirdness" plotline in the upcoming story, since a fairly significant piece EoD left hanging was the fact that the Aetherblades spent years in the fractals and managed to either avoid becoming fractalized, or their fractalized versions managed to leave the fractals, both of which would have pretty significant implications given the existing fractal storyline with Dessa and Arkk. Bringing her back would be a great way to simultaneously explore that loose end AND finish the excellent character work they started with her.
