Haven't seen many options for Armor/Shields for Druid tanks.
Dragonscale - Black/White/Blue at 14, Green/Red/Red at 20+
A few misc like Parasitic but not heavy. So no heavy armor until 14 at least, which requires Gianthold pack. Then you have to wait until you can get 20 Epic scales and some other requirements wearing level 14 armor probably up to level 25.
Shields - Madstone, Alchemical
Here you can at least use Wooden Heavy/Tower, but unless you have Madstone/Alchemical already, you will wear them till you can pull a Madstone/Alchemical. Weathered Targe and Carved Bone shield are weak.
For a new class who has one aspect designed for tanking, they need more items for it.
There are many quests at low and mid levels where Bone, Flesh, Crystal, or darkwood/darkleaf armor could be added. It is sad I will have Heavy armor prof and nothing to equip for multiple levels.
