I find the entire protectorate system, along with tributes, obsolete and left half unprogrammed. In my recent RB campaign the Huns, with their anachronic Austrasia, attacked me. I could've beaten them albeit pyrrhically but they offered protectorateship and I accepted after demanding and taking back the city which they had -quite pyrrhically- taken from me the turn before. No more than two years later they attacked (and are now gradually becoming a page in history ).
