12 vampires on level 121 might not even be able to take a tier 3 creature with morale bonuses from the Griffins. At the same time, 160 Trolls on average for Shahti can already take a tier 2 creature! on **111**... Ideally, Necromancy should be banned, not Vampirism. You don't feel this as much on L, but on XL (the map tends to get boring), your opponents with Necromancers will start having big problems.
