Oh man, there's no way I'd give up my wand and scroll mastery enhancements. There's at least 5 other people in my party doing damage - I don't need to min/max mine. A basic investment in Divine Punishment will do.
I agree that every divine should have DP and a radiance spellpower item and crit chance.
Not every divine needs to min/max for it.
If you do, more power to you. It looks like a lot of fun. Maybe sometime I'll make a smiter FvS.
