Television appearance and video game appearance aside, DC does have other Batgirls besides Barbara Gordon. So Why doesn't DC focuses on them more often they do with Babs ?

Popularity aside Barbara isn't really the FIRST Batgirl in the Batman series as that fell to Betty Kane as Bat-Girl. So why isn't she given enough respect ?

Same for Cass Cain and Stephanie Brown. DC keeps on promoting changes in diversity, but can't truly see what's in front of them and revert these two back to normal status in the REBIRTH/New 52 line.

Honestly it's like DC doesn't Care about the OTHER Batgirls besides Babs. It's all a cash grab if one were to look into it.

As Bat fans and Batgirl fans what do you think of this ?
