Except we don't know what kind of powers Elmenhilde has. Gasper was well suited to be a Bishop because he has magic talent, not to mention his Balor View is very magic-based. Elmenhilde may have skills that better suit a Rook. After all, look at Koneko, you can't judge a book by its cover. True vampires use shadows and such, but even Koneko uses "magic" through her senjutsu. I think we really need to wait until she fights.
