Using FMs as gorvernors or as army?

[Mister V]

While it is true that governors matter for civilized factions (they're a matter of life and death, mostly), sometimes it helps as barbarians. Like having a governor with the Miner trait (or is it Good Miner?) in a settlement with mines, obviously, it helps your income tremendously. I'm not even talking about the large empires, where they're extremely useful against unrest.
Sometimes though, even with civilized factions, there's an excess of young ********, so I get them together and give 'em some factional troops, some mercs, and ship to another random coast of the Mediterranean to raep and slaughter their way through coastal cities. Last time I think it was the Roman Rave 200(BC) in the Levant... I'm pretty sure I had 9 young dumbasses in that army. Roleplay, I guess...
