I've lurked for awhile now, but this is my first actual post. After having read something of the suggestions for Bard regarding morale stacking I thought I'd bring up something I've been doing in my own house rules for this.
The majority of divine magic effects that granted morale bonuses I changed to sacred bonuses. I've always like the sacred bonus, but it doesn't seem to come up much. I did this with most cleric spells as well as a number of the Paladin's abilities as well. It feels thematic and right, and avoids overlap with the Bard's abilities, as well as those of any arcane caster as well.
