Far as the Aussies, the odds of them seeing combat, are 1%. British cannot afford the MMPs to even upgrade them, let alone reinforce then transports, and fight the Japs (Japanese). The odds of a top rank player even fighting anywhere in Asia, about 3%. Maybe you'll get some action from India, into Burma. The Pacific Ocean is like "On Golden Pond", all still and ducks floating around. Zero, Zeroes and zero action. Players mow over Russia.
Yes, that's my point. Playing as the CW I haven't used AU/NZ forces once. They just sit there forgotten because I don't have the MMPs to make them useful - but in the real world they were transported to Africa, defended Tobruk, were shipped to Singapore, defeated the Japs in Papua etc etc.
Not being able to do anything with the ANZACs is completely unrealistic. The game should be fixed to allow their participation.
