Upon entering chaotic, you will want to upgrade your base. Doing this requires the violent method of destroying your old home, after of course traveling to it. As the secure bases are only reachable by the means of zeppelin or disabling the security measures and making yourself vulnerable, it is such a sad thing to see your peasants and zeppelins disappear when you destroy your town.
Destroying a nation or a base should not destroy zeppelins or (town-purchased) peasants or their housings. It only makes it a hassle to go back to town and pick up your items again, or in general going where you want to go. If you're in the only safe(from anything but legion) base north-east you have to lower your bridge and walk. If you are in the western-most, you HAVE to get a zeppelin to get back to the mainland. Good game if you don't have any allies who can share control to your or anything alike. Secondly, it would be nice with a upgrading option on the camp or nation town hall to have a upgrade feature, to save the trips just to destroy and upgrade your home(Thus losing your zeppelin and peasants).
