What a phenomenal map! Every faction feels unique. Still getting a feel, but for example that the freefolk lack any trebuchets or catapults (which feels fine lorewise) makes me use them very differently than a sieging faction.
I don't know what the consensus is on balance right now. I dunno if Angmar is supposed to get whomped on quickly, but a very minor tweak that might favor them would be to lower PU in West Angmar, East Angmar, and West Rhudaur, and increase it in West Mountains of Angmar, East Mountains of Angmar, and North Misty Mountains. Or something like that. I'm scratching my head as to why Ettenmoors is worth 3 unless you want to encourage fighting over it?
