After continuing to play PA I have three more ideas/suggestions. 1. break up the Kingdom of Anatolia into 2 or 3 smaller kingdoms. Whenever I create that Kingdom as a viceroyalty it always become unwieldy, ie the Viceroy causing wars by trying to revoke several governors and counties. Maybe use the late Roman diocese of Asia and Pontus for kingdoms instead. 2., if possible, make it so vassal Kingdoms don't have their own patriarchs. It makes no sense when my Serbian governor makes himself King/Despot of Serbia and gains a Patriarch. Finally, and this is super minor, give Samos a de jure capital.
