I love Ermor myself, although I hear it isn't so great against human players due to the ease of banishing it's undead armies with priests... I haven't played any humans yet(damn LAN bullcrap

I paid for the game, i'd like to think I can play it.

)
But I haven't managed to field armies nearing 2000 units with anyone else yet =) It's really impressive the ease and speed it takes to get huge armies that can easily steam roll over the living.
They start with a 10 death gem income too, which I find invaluable myself.. Also on the scales - you can max death, cold, order, and productivity - with almost no real problems. Gives you ALOT of points for magic spheres. Too bad I think that Ermor doesn't really have any sacred units - starting with 4 in every sphere would be damn handy for your automatically blessed units.
