The Balefire Butcher, Dryklash, was famous in Kyros's former life. It was this orc that became one of the Champions of the orcs that were responsible for the deaths of two Champions of the human alliance. His strength was marvelous, and his followers were numerous.
Orcs had a different class set from humans due to their tremendous advantage over humans. A regular orc was larger and was not suited for some human classes. They could wear more armor and wield larger weapons. While humans devised more tactics and magic to defend themselves, orcs mostly focused on brute force.
