I see nothing wrong with Beyonce's costume. It isn't like she's walking out in a g-string and pasties. What are we, a bunch of Amish? She's a performer, it's the Super Bowl, and she has every right to wear something interesting. Who wants to see a headliner wear something boring, anyway?
Indeed, when I saw her, it reminded me of the Witch Lace bodysuit from Magic Pack 2:
http://wiki.cohtitan.com/w/images//5/5d/SB2_Witch4.jpgThere's a difference, I think, between Beyonce's witch lace and what Blade & Soul is doing. Beyonce's leotard is made to be seen. It's attention grabbing and fashionable, which is what a performer (or a super hero, I might add) wants to do.
Blade & Soul is just pervy. It's looking up the skirts of teenage girls to reveal things that are meant to be covered up. There is no style here, just raw voyeurism.
That's something we ought to think about when criticizing Blade & Soul, or when we compare Blade & Soul to CoH. It isn't about how much--or how little--flesh is exposed. It's how it's presented that's the real issue.
