One important consideration-as of now, Oracles can quickly become old. You may be better off using your cash on Earth Readers if you plan on researching with them. Also, if you can afford to equip them, they make a fine fighting force-they're all priests so undead will melt before them, and they all have atleast some magic. Add a heavy combat bless, armor and weapons, and you've got a superlative fighting force. I do think Agartha is a tiny bit weak, though. Two changes I plan to make are increasing Oracle max age, either increasing the size of Ancient-level Agarthans or adding/modifying in some size 6 Agarthans, allowing earth readers and oracles to have a small chance of preventing bad things from happening while increasing their price, and possibly adding Beholder units and maybe another type of "monstrous" unit-these changes are a little overpowering, but I plan on tweaking other nations as well.
