What is really needed is an alternate transport…LST IN house rules players would be required to buy them in order to perform invasions, regulating the AP to transport from port to port only.
this is a 0-0-2-5 unit, which carries 2 land units of any type direct from a friendly land space to an enemy land space separated by ONE SEA ZONE. This alone makes the game greatly more realistic and island hopping will be the norm as well as realistic drop zones for invasions.
Now the allies must stage in UK before going to France, allies will need a foothold in Africa in order to invade Italy. No more direct invasions from New York to Norway nonstop.
and no more of these guys sailing around the world in transports plucking off areas where you cant send men fast enough because infantry moves one space in 6 months, while a ship moves double speed and lands guys behind the lines…poppycock!
Obviously ports will be more important with these rules.
