After the division of The Roman Empire all units go to the Byzantium. This leads to the situation that the west seems to be very weak to AIs and suddenly most of germanic tribes attack the west. There should be units granted to the west in the moment of creation to fix this issue.

There is also a problem with institutions. The west starts with only writing embraced even though the next institution is already present in all its provinces and is embraced by the Byzantium. To fix this I suggest that the west should start with all institutions that are embraced by the Byzantium embraced.
