Yeah, like in multiplayer have factions like Mountain Bandits, Forest Bandits and Sea raiders (you could include the other bandits but they aren't very important) And then have the classes set up like - Forest Bandit Archer or Sea Raider axeman or something. Or throw them all into one faction simply named "Outlaws" have Forest Bandits function as archers, Sea raiders as infantry and Desert Bandits as cavalrymen or something.
