Have vampires ever been really strong?
I have had no dealings as yet with them in Dom3, but in Dom 2 I had vampire lord takes over a province, random event. A vampire lord + 20 vamps + a horde of undead. Scared the hell out of me, but when I attacked with a army of national troops, playing Machaka at the time, my Black sorcerors, priests and spider mounts wiped them out real easy...
A long way from my AD&D roleplaying days, when we use to abandon the adventure and run away at even the hint of a vampire. 1 level life drain...shudder...
