Could be. But in that case, I would view A-F as "very strong". I dunno about Bambietta, we don't know anything about her yet, but Äs Nödt is obviously a fearsome person to fight because of his fear inducement ability.

But until we know more about each Stern Ritter, I think the order of power is random. I think the letters signify their special ability, not rank them A-Z from strongest to weakest.
