I think I understood what your ideas where - but that's not how it works out in the game
What will a player do if his pretenders quells a certain amount of unrest in a province each turn? He'll crank up the taxes without needing to patrol (and lose some pop that way). Therefore it would be easier to simply let the province generate 10% more gold ... .
Doesn't very high turmoil scale result in 0..5 points of "base unrest" any more? Therefore, if you pretender quells unrest, he is in fact spreading order .. or am I maybe mixing something up from older versions of Dominions ???
