We should make it so that each of the large cities (or if they aren't cities, whatever they are called, the ones that have like 7000+ troops and are mostly unoccupied at the moment) give a bonus to the faction that wields them. No Strat bonuses, but maybe C-rpg bonuses.
Like, for example, each one could give one of the following
+5 gold a tick
+10% exp
Less chance to have to repair items.
Would encourage players to take and fight over these cities. Maybe add something like must be in the faction for like a week to get these benefits, so people just don't abuse join factions that have a lot of cities.
