Currently playing as Germany, I have almost no spare soldiers left of North or South German culture to build new brigades. Is it a good idea to use French soldiers to raise new brigades then? I have quite a lot of French culture soldiers from conquered French lands, I also have a lot of African culture soldiers from my colonies, is there any disadvantage of building armies made up of troops that don't belong to your culture?
I am thinking about this because in my last war I had quite a lot of mutinies, where a brigade or two in your army would suddenly take up the rebel flag and turn on your forces. I assume foreign soldiers are more likely to mutiny, apart from that what are the disadvantages of using troops of a different culture?
