Never say never!
People will use anything to their advantage. Why should advies be any exception. What advies were intended to be and what they are are two different issues. Let them be weapons on BT alone. It is a high magic island. I don't see why advies can't be wizards. Nobles should be allowed to build hogwarts so they can train these battlemages to blow up !@#$ty realms like Bara'Khur.
