Make it so priests get +1 DF per person they res in war instead of kill. Waiting for a priest to lb a stone is really annoying. That or you set up a stone to get LB'ed and someone else takes it.
Possible arguments:
it makes it too easy for priest to get df - gives priest an incentive to relog when they die instead of running as a ghost and not benefiting their nation
can be farmed through suiciding chars - kills can be farmed too
