If you guys that are making the mod havent figured out unit names yet besides things like elite and veteran spearmen you guys could use that factions/units champion/hero/lord/ names. So for dark elf spearmen it would go like this: Spearmen, Lordling Spearmen, Noble Spearmen, and finally Highborn Spearmen.
P.S. Can u tell me which faction the DE are being modeled after, cause i no chaos is denmark, brettonia is france, and empire is the holy roman empire, so if u can tell me id really appreciate it, thanks.
