Plus a bunch of other stuff people have said about Babs growing and being better as Oracle.
Plus my own "I didn't really like her as Batgirl, I love her as Oracle."
Plus "Putting Babs back in spandex would be insane." - Gail Simone
Plus (and this isn't one of my main concerns, but it's there scratching away at the back of my brain) right now we've got a handicapped former Batgirl that can kick ass and be useful, and an Asian Batgirl that can kick ass and be useful. Getting rid of both in one go? Can we please not?
