Haven ROCKS!!!!!!!! Battle Griffons are just awesome. If you play as Iris and add Vampirism to them in the final stages, you get a truly monstrous killing machine; even a Barbarian with fully upgraded Darkness skills can't do anything! My friend (we were playing on the same computer) was almost crying with frustration, but all he could do was keep sending his magnificent melee units (including Blood-Eyed Cyclops) to be slaughtered by this beast:)))
Regarding Archangels - can someone clearly explain how much damage his spell deals?
