The map is amazing.
But for the criticism, my problem with your map is the same one I have with a lot of Edain fortress maps. I belive that fortress maps should have at least three players outside the fortress in order to give the fortress player a hard time fighting multiple enemies, after all he has a fortification. I believe people who play against AI will agree with me on the matter, even though AI has improved a lot with Edain 4.
So my suggestion is expand the map and add one more player outside Amon Sûl, but try not to put it in place of the outpost flag, they're precious for invading armies.
Two gate is nice.
