I'd love to see the Adventurer class more involved with the BM world at large:
- hunting bandits for bounties (which would improve control)
- telling tales (which would improve morale and maybe weaken control)
- doing some of the messy, hands-on things infiltrators can but probably shouldn't because of the risks like sabotage and murdering militia
- doing a bit of banditry themselves like robbing tax collectors or thieving or running protection rackets in cities (which would gain gold and lower control)
- being able to set up gangs/parties and secret societies so there could be thieves guilds, etc. without noble involvement
- smuggling and black marketeering
- being lay clergy or rabble-rousing demagogues
- kidnapping for ransom
- being those anonymous scouts and secret police
- becoming a wizard or sage
Some of these would also require new shiny things to spend the extra gold they produce on.
Love the hunt bandits idea. I don't think an advy should be anywhere near able to rob a tax office. The option should just be "rob peasants" and it not only gains them gold but also lowers realm control, morale and prodution.
