My favorite take on a “Druid” anywhere I’ve seen is in Stonetop - because they’re a priest of the Earth Goddess before all else (and no shapechanging, but they can borrow power from spirits and natural beasts).
The Druid has always seemed to be a bargain (other class) that can change shape; or does things that seem at odds with the core philosophy of somebody that.
Edit: in fact, I wonder if Druids aren’t best left as NPCs (wise people in tune with nature and life); and we have explicit “nature’s tooth and claw” via a more Ranger/warden thing to use 4e primal examples.
