We will use free upkeep under certain circumstances and political/governmental situations. In EB1 the availability of units was controlled through availability of money and that's why the Lusotannan had to disband some units early on, to get finantially stable. In EB2 we can control the unit availability directly, so it will be easier to have a more balanced start without the need to disband. We are trying to provide these slow-moving factions the means to get money, namely through raiding. We can achieve this through the use of PSFs, since they represent minor settlements that can be conquered (without siege battles) and return money while they're controlled, and through traits that give money while the general is in enemy territory.
