That's because DC doesn't know. And writers only get so long to try and make their mark before they're pulled. I mean, it could be worse, she could be Superman whom they don't care about so much that they've moved effort toward a shitty new character. But they don't know her and haven't cared much to know in a long time, just so long as a book is consistently published.
I wish this run the best but you just never know when the rug will be pulled out, regardless of quality.
