Someone is angling to win the map prize
Excellent imagination here. Games will be really slow paced expansion wise with all the heavy neutral defenders which is a nice change up from so many other maps.
Hard to tell initially about balance (for example there are 3 cities with items but not equally spaced apart and not equal quality items and the start positions aren't perfectly symmetrical) so I hope you will regularly make updates to the map because it should be a good one once it gets played a few times.
