I think she's the last thing the division needs, because she'll allow them to do what they do best on the booking/writing front:

Hotshot established names.

She's a net gain that will allow them a thick layer of protection from their worst tendencies.

Those women are over because they're too busy putting WWE and Stephanie over. They're actively puttingnover "History!" Instead of the women.

The wrestlers didn't get exposed.
Vince and his creative team did.

I'll give the caveat that since the trash writing isn't going to change either way, it's better to have a ready-made band-aid in the box, but Ronda is yet another star they don't have to actually do the work of making, same as they get by with boring ass Brock stories and rinse, wash, repeat matches on the strength of a name.
