At my table, the player (and only the player) gets to decide what their own character does or doesn’t want to do. While druid NPCs might not wear metal armor, a player is free to decide their druid PC does want to. Druid NPCs they run into probably won’t approve.
Yeah personally I think I'll create non metal alternatives so they can wear the better armor types.
I would have just made them proficient in leather and hide. They're in that range between Wizards and clerics for armor use.
