Of course it can also be useful to keep enemy dominion around.
I'm playing around in SP with LA Mictlan, terrible scales to finance the abusive bless. While you don't benefit from good enemy scales, even neutral scales can be better than what you've bought. Targeted preaching, or in Mictlan's case blood sacrifice, lets you bump your dominion up to reduce enemy scales that are bad, but leave your dominion low to keep neutral scales in place.

Does anyone know the mechanic for scales changing actually is?
