While I enjoy Mr Miller's novels and his tongue-in-cheek approach to the setting I'd take what he writes with a pinch of salt. I'm pretty sure he had orks using bolters in either the 2nd or 4th book (a throwback to 2nd Edition 40k), so I'd be cautious of declaring all his works canon. Which, of course, is the same caution I'd advise you to apply with any BI novelist.
Anyway, I don't see how this should be an issue. If a player wants to chase after encounters of a sexy nature the Sororitas is the last career he should go for.




I still use the thing...
