Orcs are a very strong combat race. Without Subjugation and/or Berserk, Necropolis won't survive on a large map, but Darkness will be suppressed; Subjugation is especially unpleasant. Berserk in the first turn isn't that scary.
Subjugation is great, and we cast Vampirism on our dragons. Then, their "Wrath" won't be scary anymore).
