The German ship is signalling distress! Â Its flag is upside down. Â
I was considering super battleships for Japan (and maybe USA) only. Â The plan was:
30 cost Â 5/5/2. Â Takes 3 hits to sink. Â A functional port can repair only 1 hit per turn. Â No limit on how many you can build. Â If limited only to Japan (Yamato class), super battleships cannot move through the Panama canal.
Never tried it though, we always end up playing by the book. Â
Edit: I think I may try some of your idea. The first hit is 'free' and the second applies damage. This means that even when going fresh into a battle while damaged it would take 2 hits to sink. A 30 ipc unit needs to be tough.
