[Divine Favor] Is Smite underpriced?

[Dustin]

I'm generally in love with the Divine Favor rules, but something just caught my eye. Smite (Divine Favor p.12) gets an Accessibility limitation of -50% for affecting Malign Supernatural Beings Only. Does the Malign part seem like a bit of a point crock to anyone else? It's a bit like taking Enemies Only as a limitation. This is basically a -50% cost break, to have an Area Effect that you can lob repeatedly in close quarters without worrying about your allies (supernatural or not), and without the need to buy Selective Area +20% (B108).

Affecting supernatural beings only is a legitimate limitation; you can't Smite a dire rhino, I'm cool with that. It's "malign" that I'm concerned about.
