This map is exactly balanced for two players/teams.
You will find special territories that are call "Rest of the East / West". They are like reinforcment, each of them is a 0-supply bonus by default. You can set them to a more-than-zero value and play with the "From the far East / West" distribution (I like when only one is distributed and other are blocked by 500 neutral armies). You can also disable those territories by setting negative bonuses.
Great map - equally suited for 1v1 or larger FFA and team games. It is well-balanced and entertaining. The bonuses are evenly distributed. For an added challenge, players can also dial up the negative bonuses on the ships or else make them massively armed wastelands (or both, I suppose).
One missing connection I noticed - Ma figal E to Ma Chazali E
