Rulership demands complete attention, it's not something can be half assed and still get good results, going Markgraf is the option most likely to complete overtake our time and leave any research and adventuring in the past, i just don't see Mathilde not giving the work her all.
We are going to have advisors, but we still need the AP for advisor actions, it's not going to be "Let Kasmir handle it", it's going to be "Use your religious advisor to instill this practice in Helfenn" with the corresponding AP cost, there is no going around that, unless we are hands off and become one of those counts hunting in the woods while someone else rules in our place, and after that what's the point?
