Which faction poses the greatest challenge for the Dwarves?

What should we do about the plague and unholy words? As I said, this is my main tactic. The Necropolis faction sits in defense – while the Dwarves with their damage output tear them apart (if the spirits allow), we will keep cursing. Against Armageddon and Priests, we take Ice Shield + Undead Magic Protection = 70% protection from fire, and if we add defense, it's 85% in total. We can even do without Berserk and Subjugation. True, the Dwarves can rush at the beginning (tested) due to their defensive units, but this won't work in the mid-game.
There's no need to level up luck for the Necropolis faction; it's enough to take Archmage, as we will be attacking the Dwarves with magic. Even though their units are tough, what's the point? Yes, Avenger, if you're going to speak for everyone, how much have you actually played as the Necropolis faction yourself?
