-1 for having no leader, or having your leader killed during combat makes sense to me.
-1 for being more than 2 heat/cold levels away from your preferance makes sense as well.
+1 for your god being present on the battlefield.
I would not mind a new Level-2 holy spell, "Warrior's Blessing", same area (or slightly smaller) as bless, that gave +1 morale to non-sacred units for the duration of the battle. There should be some advantage to having a representative of your God in battle with you. Otherwise, why would modern armies (which do not AFAIK have sacred units
) employ chaplains? This also might just be open to some themes or nations - Ceremonial Faith, or Marginon, IF Ulm, Vanheim, for example... though I'd like to see it for all nations.
I'd also like to see additional dominion effects, for all non-mindless units. Perhaps something like this (cumulative):
Dominion......Effect
