Did you watch the tournament? The Dwarves were crushing everyone. They need to be nerfed, and severely. The second overpowered faction is Humans. Training 20 Paladins a week is excessive. Either the second building for retraining should be removed, or the cost of training Paladins should be increased. Let them train Archers. Dwarves should have the Rune of Exorcism, Elemental Resistance, and Magic Ward banned. In the tournament, I think everyone saw that they are completely overpowered.
The Undead rely on numbers and the self-sufficiency of their army; the fact that they have low stats is not a problem at all, because on the second week, the Necropolis can be built, and the Necromancer doesn't need to enter the city for two or three weeks, just clearing out neutrals and gathering an army.

Demons are usually played as archers, in the Chaos league.
