[Vicious Love]

Heh, tell me about it. I play Black Forest Ulm all WRONG. I know I'm supposed to rely on regular units far, far more than on my immortal elites, but I invariably end up taking sloth 3, spending all my gold on temples for a Dominion push, and just assassinating every enemy commander that comes my way with Black Hearted vampires.
Once I research Blood 7, I also like to have a greater vampire or three around, summoning immortal goonlings. Useless in small Groups, both as troops and as bodyguards, but once you have about 60 of them, you're indestructible in your own dominion.
