a possible solution to this would be to make it so that in team games you are capable of setting up attack/transfer orders from allies territories whether MA is enabled or not.. It could not be universally allowed with or without communication unless a global movement allowance similar to how MA games allow you to attack from any territ to any territ.. and I don't know if Fizzer wants to Implement something like that for normal games..
