Morkus from Orkus
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.
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.
