and now for something completely different (mebbe... well, probably not

)
Let us imagine our fantasy land without allusion to history. Each area of this land is in one of three conditions:
1) Neutral - Neutral provinces maitain an army to defend themselves so that they don't pay taxes to anyone.
2) Conquered - Conquered provinces have had it proved to them, at the point of the sword, that they live at the sufferance of their conqueror. They pay taxes, at the rate set by the conqueror, because they have no other choice. Even if the army isn't "there", it's within a few days' march as far as they know.
3) Home - The only possible argument in my mind is that perhaps home provinces need to be treated better, but it
is the fervent, worshipping home of the pretender and likely to put up with abuses for the sake of their lord.
I'm generally of the opinion that a 'trick' that can be easily performed by any player is fair game. It merely adds a layer of complexity in considering how best to use the trick or in calculating how best to defend against it's employ.
