Bretonians may have industry, industry which can be run with slavery and threats since they got their own raw materials they dont really need money, only patriotism.
Fact is, i dont think the liberty would "mind" that much. If they get weapons from the outcasts or the mollys for that sake, it would only show something else. That the outcasts got a kind side. A side with huge benefits to it.
Though we cannot have a BAF using cardamine to boost their skills, we can have a BAF Wing allowing the use of outcast weapons.
about the KNF situation
I have seen corsairs, even benitez, being chased out of kusari by KNF officials.
