Vampires are now raised from all creatures of tier 4 (succubi, griffins, lizards, shamans, etc.).
It seems you didn't quite understand the mod's concept. The idea is very simple: by killing creatures of a specific tier, you raise creatures of the exact same tier, but belonging to the Necropolis faction. For example, when killing titans (tier 7), you now raise spectral/astral dragons (also tier 7), whereas in the original game, death knights (tier 6) were raised...
I understand. This concept has been around for many years, and there have been various implementations, but they all had flaws. For example, you can't raise dragons from angels because they are essentially immaterial, just like unicorns... In short, balancing is needed to make the mod popular!
