i think it's because those who like the slash/wincest stuff, the dominance/kink stuff is ... not necessarily believable but easier to write. I don't read the het stuff because the chicks always annoy me. except your stuff. and charolette's. and chrissy's. I just... majority of the het stuff the chicks are nauseating. I'm so picky. Ugh. Anyway, yeah. Plus it's really hard to find good ruby or bella recreations. they're pretty complex characters with a specific voice and pairing those two with the boys are kinda... i dunno, weird? Anyway that's just MHO.
