How shall the partisan-unit be re-balanced?

[Optimizer]

The partisan idea is good, because it balances the game in favour of the defender. Partisans should be available earlier but be weaker.

Remember Colonization, where a percentage of your colonists were tories, and thus were a minus when defending your colonies against the king?

The idea of resistance could be implemented so that the portion of production that the conqueror loses due to disorder/corruption can be used by the conqueree to build and maintain guerrillas.
