Vlad! Markel is good, but it depends on the presence of undead on the map, meaning it's a matter of luck, and I don't like that, plus innate leadership – who would have thought to give a Necromancer leadership as an inherent trait, although on the other hand, you can replace the ghosts with someone more useful, but I don't like that either. Lucretia is strong, no doubt, but on the other hand, vampires aren't what they used to be. In the second, third, and especially the fourth games, they were simply dominant, but now... no, they're still strong, especially under the leadership of the Vampire Princess, but in my opinion, effective resurrection is more important.
