Haven vs. Necropolis

A weak archer is the only downside of the Haven faction :). A mage hero increases the damage of Vestals and Luminaries, and Light deals more damage to undead than any other type of damage. The rest has already been mostly listed: 3.5 flying units, blinding Luminaries, the "Aura of Retribution" with Seraphim tanks... A worthy faction that can definitely defeat Necropolis. There's no need to cling to the undead so much ;).
