I agree with Skull only in that his statements are true for maps of average size or smaller, and even then, only if the opponent isn't too evenly matched in experience. As the map size increases, things become more complicated for both the Orcs and other factions. And if we're talking about maps generated with a non-standard, larger-size generator or in a late-game scenario, then you can easily run into a situation where you're facing a heavily upgraded opponent...:D
