I'll repeat what I stated before. The reason this happens is because the map is borked. All of these countries have their number of provinces reduced by about 2/3rds (or more) versus what they should be. Thus the badboy and stability hit cost of conquering them correspondingly goes down by 2/3rds. These are big, big countries. Countries that in this era had as much land area, population mass and GDP as the entire area of the Low Countries (Belgium, Holland, Luxembourg). But in EU3, they have a negligible ability to raise defensive armies, so in the first war vs. Ming, they get whacked down to a one province minor and they they disappear a few months later as some other minor abosrbs them. It's like France annexing the entire Low Countries in a 6 month war. Until the map is fixed, any attempt to adjust play balance in this area just leads to wacky, unhistorical setups (see mods).
