How is it feminist? Robert Jordan wrote that the male half of the Source was tainted by the Dark One during a particular event, thousands of years ago, so only the women can use the Source. That's a key part of the story, very important, later on.

What's been changed is that the characters aren't so innocent country-bumpkin, and they are more diverse than one would expect from a distant mountain town far from anything.

I am okay with it being diverse, so that more people can relate to the characters.. I don't see how someone can think it's been feminized, though..
