Lvl 1 infra makes the island hopping campaign a real hell for Japan... At least if you try to invade the islands owned by Netherlands and Australia. Some islands can't even be completely invaded, because of a batch of lvl 1 infra provinces. Also, makes invasion of Australia just like invading a bunch of islands, because when you take one port, you cannot go far without being trapped by lvl 1 infra. Then you have to go back and invade a new port... then again and again and again. Just... awful. There should be some sense in the amount of lvl 1 infra, Maybe lvl 1 infra areas should just have like an attrition x5 or something, or maybe there shouldn't be as much lvl 1 infra. I hate it when you're going for total conquest, you cannot have some islands because of all those low infra areas.
