There was a patch (for SoD) named after Chaos, where necromancy was removed as a skill, and the last seasons of Chaos League were played on it. Vampire Lords remained. I haven't tried it myself, but according to rumors, it resulted in a more balanced gameplay.
A similar function is performed by the necromancer patch in The Eastern Expansion.
