Ermor balance?

[Heironeous]

I can definitely see how things might balance out later in the game, but it's the early going I'm more concerned about. If I had started next to him he could've overrun me fairly easily (like he did to Man). Masses of priests aren't really an option in the beginning when you have only 1 castle. He also had the luxury of being able to invade many provinces at once, which puts a lot of pressure on the defender.
