Orcs – discussion about the race.

Goblins aren't the best unit, but they're surprisingly good at setting traps (if they're a Trapper). Place a trap under the feet of a Paladin or a rider on a lizard, and there's a chance they won't make it, which can be very helpful. Otherwise, I don't use them much, except maybe to finish off enemies. And you can never have too many goblins, especially if you have the "Wrath of the Horde" skill.
