There were many things the writers could’ve done with her, like having her hunt down Finn and Rose on Canto Bight as they are looking for the code-breaker.
I think that would have been a fantastic part of the story. Give her some depth as an angry captain going AWOL to hunt down a couple who she feels outsmarted her. Great idea. Would have also made the casino story much more interesting and meaningful.

Far better than shoehorning ham-fisted obvious messages about “animal cruelty being wrong”. Also have Phasma kill DJ instead of having DJ betray Finn and Rose so it wouldn’t come across as a knock-off of Lando betraying the heroes in The Empire Strikes Back.
