Which faction do you like the most in Heroes of Might and Magic IV?

Why isn't it fair? Nature also summons a 3rd-level creature when the summoning skill is maxed out... I don't see any unfairness.

Well, Necropolis is a slightly overpowered faction, regarding necromancy... Pandora, vampires will be more useful than earth, fire, and air elementals. Water elementals aren't always available.
