As stated elsewhere, I can hope this is good and that Cass doesn't end up being the 'super-awesome fighter who always gets beat up by the villain to prove how good they are'. DC's track record using Cass since her original solo series is universally bad - even 'Batgirls' was kind of crappy, despite the writers being all enthusiastic about having Cass.
But if she doesn't get any exposure, she will disappear again, so that much is at least okay.
