I can imagine that by midgame Ermor is darn hard to beat. Surviving to then is the trick. I found that versus 12 impossible AI opponents, I cannot wait for the freespawns. Archbishops summoning horsemen seem to work really well. Especially once you have a dozen Archbishops or more. Without those horsemen I just wouldn't have enough troops to expand with my usual berserker enthusiasm.

Do you limit your expansion and focus on research? I admit that's an approach I have ignored to date.
