Just a quick one - haven't started a campaign yet, for now reading expiriences, recommendations etc. How does paying for all armies in field - and primarily I mean armies led by captains, on their way to some castle for retraining/upgrading, or reinforcments for main armies - stand up to increased economic challenge? In my current campaigns, I have usually up to 10-15 small armies of max. 2-3 units going back-and-forth from main armies, to castles, troop production centers etc. Do they suck up too much cash?
Also, AI always have many small stacks running all around their territories. Will this put them at handicap?
