Notice I also gave Rome 6 IPCs. If Austria starts building transports Italy should have the sense to leave a strong garrison in Rome, or get its allies to join it in obliterating the Austrian fleet.
I actually think Rome is more defensible anyway with this arrangement, as Austria cannot grab Naples by land and deprive Italy of another 2 IPCs.
The other main objective is that the SZs bordering Africa have no mines, which should make naval combat more lively; the CP fleets can link up, or invade north Africa.
Albania is less open as a gateway into the Balkans for the Allies; Greece is more attractive now as it doesn’t border Constantinople.
