Do you think that CA might ever introduce attrition or supply rules or if it is even moddable into the game system? Like if the army is outside a city it loses troops to desertion/disease while paying maybe double in supply to reflect foraging (though if its in enemy territory the enemy pays). Rates of attrition could be lowered depending on the presence of a fort (lower desertion) or a city (does not desert or desertions are made up for by immediate impressment of volunteers)

Just thinking out loud,
