I've failed plenty of times against the AI, usually when there's an AE Ermor or C'tis involved. Dunno why I lose to C'tis. I find that I have alot more fun playing when there ISN'T a death theme to have to deal with, since the other AI nations never have a chance. It's pretty much given that you'll be fighting Ermor and probably be crushed. It's not cheating to leave them out, but if you want to fight them you better beat them early in the game, and have a solid plan to do so. In multiplayer, it's not unusual to gang up on a death theme just so the dominion doesn't spoil the... spoils
