well tbh a guy unable to protect himself,how much good he would have been for ruiling an already declining economy country with nothing to offer and empty states,it had nothing good and just issues which i don't think even greatest ruler of past era would go around solving so forget about that guy even thinking of it,then there is issues in start,when central was weak and on verge of war.
Ryen was best thing happened to central tbh,wether he take good path or few evil path.
