What's wrong with dominatrix
Are you talking about the New 52 one where she found an erased file on her while working? I think that one just got completely ignored.
The official New 52 Catwoman back story they used starting Batman Eternal was that she's the child and heir of mob boss Rex Calabrese that predates Roman Falcone. She didn't know this and only found out after she received his letter during Eternal. That's how she became a mob boss in the later stories.
That said, those two backstories don't exactly contradict each other except that Selina was Russian descent in the earlier version and Italian in the latter.
In Rebirth she was raised in a foster home, but that's all I know.
As a child, I prefer the Cat Queen of Crime because Catwoman having pet tigers was hardcore. It took me a while to warm up to the fact that she doesn't have henchmen and secret lairs in the modern iteration. This is why I like the mob boss version because it reminds me of the crime queen of my childhood.
What did warm me up to the solitary cat burglar version was the fact that the whole wild, feral and free aspect of that version is very cat-like. It fits what I think Catwoman's personality should be.
The back story doesn't matter that much for me. The reason I don't like the prostitute version is that whenever some
men want to make things Noir, they always make the villainess a prostitute no matter what they're usually defined. Selina by Miller and Harley by Azzarello.
