Haven vs. Necropolis

Then Necropolis will be weakened as well ;). Haven is indeed a powerful faction, with the best faction ability :)! But you need to know how to use it. By the way, they also have a significant advantage against Necropolis: Vestals and Luminaries have a Light Strike attack. In addition, the healing of Vestals and the healing spell that can be learned by the hero are effective against the undead! So, Haven is a real alternative to Necropolis; there is no need to weaken it :).
