I’m not saying that vampires are weak. In a one-on-one fight, vampires are unmatched – this has been repeatedly verified (Vampires of level 4 can defeat: there was a battle of 1,000 vampires against 1,000 champions, and the vampires won). But if a Barbarian develops tactics in their army, with more Cyclops and artifacts, then the vampires won’t be able to do anything. As a rule, I gather a huge number of Cyclops, which destroy 3 units from the very first turn.
As for vampires, there can be a lot of them, and they can be obtained for free. Thanks to these creatures, Necropolis can fight almost any neutral creatures without losses, but in final battles, with large armies, Cyclops will be more useful.
