Can anyone please explain to me what the historical basis for an independent Jerusalem faction does exactly? IMO the Crusade function should be radically revamped, with a Kingdom of Jerusalem faction that spawn after the First Crusade is called, with the amount of units that it is given. That would be A LOT more interesting then having Germany, France, Burgundy, Poland, Venice etc... controlling the Levant ahistorically.
A high probability of revolts in Jerusalem means that the crusaders probably won't hold the city for very long, so you won't see something like a French Jerusalem from 1100-1800.
Admittedly the crusade function is not as great as it could be, but I don't think something like crusader kingdoms would fit in RFCE. In SoI, the Catholic homelands aren't on the map, so spawning civs with traits that distinguish them from their Muslim and Orthodox neighbors makes sense. But in the Europeans context, the crusader states were not fully independent of the Catholic countries from where they recruited their soldiers. It makes sense if you imagine it as a personal union, ex: you are the King of France and the King of Jerusalem, which are still two (de jure) indpendent states.
