Which units would you replace in the Dark Elf faction?

I wouldn't change any of the factions, but I would gladly change some of the creatures' stats. Most likely, I would increase the initiative of minotaurs and, instead of regeneration, give hydras some kind of ability like "charge" (like the rakshasa have). Then these two slow units could actually be useful in battle. Or maybe not, I would replace minotaurs with something flying, because when attacking castles, you have to rely only on magic and dragons. By the way, why were gargoyles put with the wizards? I think they would look more organic in the Dungeon faction, for example, with the dark elves. If you add more health and damage, they would be a great 3rd-tier unit.
