Which units would you replace in the Dark Elf faction?

Well, according to the Chronicles of Ashan, everything works out fine. They just appeared with 5 heroes, but if you take the lore from the earlier Heroes games, there wasn't even a mention of dark elves. Don't think that I don't like dark elves; I just feel sorry for the Dungeon faction. And Black Dragons, who have always been dominant, will continue to be so for a long time!
