im currently using elective law(some awfull stat sons) and the guy i would like as my heir controls directly or via vassals,8 provinces. however,he doesnt even get onto the successor list.there are dukes there with only 2-3 provinces and the big boy has 12. what i would like to know is; why doesnt my guy get onto the successor list(hes not excommunicated,heretic or bastard). is the number of troops that can be raised the primary factor or......?
