Should'nt the A.I.'s build policy change with every new faction leader. It would at least reduce the amount of rabble on the battlefield. Or it would put an end to the fleet production of Thrace(prior 1.2) with over 100 ships.
With the A.I. set at 1 build policy from the beginning, theres no variables so if the A.I. has mao se ????, it will have high amounts of militias to the end.
