I strongly disagree that advy reports are useless: if you k ow the approximate mobile cs of a realm and the number of nobles that's a quick guess of the region CS as well as army movements and patterns.
Either add more inconsistency to the reports akin to rumours or hearsay or add a risk of capture. Players are copy pasting the region stats alongside their scoutings, as per torture reports my character receives. In regions of vast size there is no way or reason to know all the nobles in a region.
It also adds incentive to play adventurers as there is one less uncontrollable​ reason for capture or execution.
