I feel like it's a good guideline for general Exaltation prospects for DB as a whole. However, PCs, and those in contact with them tend to deviate from the statistical curve.
Personally, I'd prefer a gem of Loyalty myself. 2ed got a crazy powerup. Difficulty five Conviction roll for any subordinates to betray you? Sign me up. The trick is getting DB Wyld Hunters to "swear loyalty" to you as a plot to get close enough to kill you. Heh. Suckers.
