The first Crisis took away her years on the JSA, and split her into two different characters. Okay, fine, made some sense. ICk and Final Crisis have apparently BONGed away her role as a founding member of the JLA. It was a nice consolation prize since they took away half her career with Crisis (and frankly it makes sense that she'd be a JLA founder), but it's different from what some people remember so it has to go. And take away her competence while you're at it. Next big event will probably take away her time on the BoP. And the one after that will retcon her out of existence entirely.
