Druids should get a visual that matches their tier every major patch with one spec getting a new model of some kind. (I.E. One new model for the tier and the rest get recolors)
With druids having a changing room and the ability to pick their form from a list we definitely need more models. This seems like a good way to fit the theme while also implementing forms.
With druids being in forms it doesn’t seem fair that we never get to show off our achievements for the tier or get a shiny new Cat/Tree/Bear to play with like a paladin in a new armor set.
