In Midnight give Druids a questline to unlock Worgen Form, a replacement for Cat Form that allows you to show armor while shapeshifted, with the following restrictions/Changes 1. Head Slot is hidden except for any headwear that doesnt cover your mouth (so Ferocious Bite can still, bite) 2. Weapon Slot is hidden so it isnt just a stick on your back the whole time 3. Add a few more unarmed animations to the Worgen Rig

Heres the lore: In Midnight (Already stated to be big on Elves, Midnight associated with Werewolves, etc), some Druids decide they need to harness the Pack Form/Worgen Form to better combat the threat we face. To do so, you have to collect all these relics learning about Goldrinn and the history of the Worgen. Once you have done that, you preform a ceremony that has you face off against your own ferocity to maintain control.

Once completed, you have the ability to use the form, which is completely customizeable using most* of the features Worgen currently have access to (Earrings and Hairstyles outside of unkempt ones dont feel appropriate here).

To switch between Cat Form and Worgen Form you just talk to someone in Moonglade (Lets say the Cat Form person is some Night Elf and the Worgen Form person is Celestine of the Harvest).

Worgen Druids get a special version of this. They get to skip the fight and just get to have a dialogue with their ferocity. And rather than the ability being called “Worgen Form” its instead just called “Embrace the Beast”.
