Morkus from Orkus
And throughout D&D druids have had the ability to don metal platemail in order to sneak into a castle. Nothing you have said has so far been able to counter that fact.Throughout D&D Druids have been leather armour clad spell casters who share a number of spells with regular clerics, who derive their power from nature, who have the shapechanger ability at some point, and who utilise simple or 'tool' inspired weapons - that IS pretty consistent. In 3 editions they had a neutral component to their alignment, but as 5E (sadly) reduced the impact of alignment mechanics that was lost. Being pedantic about the level they get to shape change proves nothing.
