A few thoughts on balancing Armageddon:
I'd like to see the initial dremer towers to be a little weaker offensively, but the dremer warriors be a bit stronger. Maybe 24 base damage on the warrior, 12 elemental damage on the building. Since the towers attack the turn they spawn, it can be a bit too random to have important early game units destroyed by them. And late game the dremer warriors are pretty pathetically weak.
The 'Anchor' guardians are all over the place in strength. You have really weak ones like the diamond elemental, and really strong ones like the Water Elemental. I think they could be normalized just a smidge.
Lastly, the AI needs to seriously stop going to war so much. It's absolutely insane that they're getting steam rolled by other worldy demons, and decide to attack you for pretty much no good reason. There should be a major diplomatic change in their behavior, only being aggressive when they aren't actually threatened by the Dremer.
