I dunno, there are so many non-religious druidic sects, the divine aspect is barely even present in the class since it quit being a bolton for umm 2e(?) cleric The Druids of both eberron & darksun are not especially religious,the druids of FR & greyhawk are practically indistinguishable.Well I see Druids are divine but the power is filtered through nature so much that it's something else.
Like chocolate milk.
Same with Nature and Primal. Magic from a Eagle spirit isn'tthe same as magic filter through nature from Meilikiki, Eldath, Malar, and Silvanus.
