I totally get not liking some of the creative decisions/directions. They didn't ask for my input either, and you just have to take a short walk to the WW boards to see me complain. I sympathize. Really, I do.
But this is a relaunch - a new DCU. There are going to be changes. Why would we assume that all change would be the same across the board? And who gets changed most? Those that are less successful. I seriously doubt it's a direct plan to toy with fans of the female characters (that's not going to make them any money). But the female characters are more likely to get more changes because the female characters are more likely to sell less, thus, there's a bigger need to shake things up.
In short, it's not about the boobs, it's about the bucks. Follow the money.
