Though I searched as someone mentioned to me. The spirit of all animal forms except Bear (Ursoc ?) abandoned Broll Bearmantle.
Also, Druids lost their flight form when the idol of Aviana was lost in 7.2 no?
But then again, If that was the case, the Worgen curse would be a non problem, would be just convincing Goldrinn to “remove” the power from the turned.
And that is why bestowed powers are too complicated.
