Which units would you like to replace/add?

In my opinion, the best unit in Necropolis was the Vampire, but unfortunately, in the 5th part of this wonderful game, the Vampire became quite strange! He got a SWORD! How can he drain life from an opponent by only touching him with a sword? And if the secret to his magnificent ability is the weapon, what kind of vampire is he then? It turns out he's a combat mage! So, he should throw away the sword and fight like his great ancestors!
