As far as I understand (correct me if wrong) Roddenberry envisioned a tough chick like Ripley from Aliens. We know Denise Crosby's role as Tasha Yar in TNG, but her role was never really fleshed out and when Worf replaced her position, Michael Dorn's Klingon character would soon own the role of chief of security. Dorn's chief of security = legendary ! Denise Crosby's chief of security = meh !
Which would mean that Roddenberry got it wrong
Its not that she didn't fit in or couldn't make a great part of the series.
As she returned in Yesterday's Enterprise or as the Romulan, her role and her work was fantastic !
IMHO she might have worked better as a engineer or second officer or popular villain etc
