I think Vrykul are too big to fit through doors, and smaller Vrykul would not be half as fun. I agree that Alliance are going to have to get something pretty special to match Zandalari druid forms and Mag'har orcs though... a Taliesin Talks is on the way

They could find a way to make Vrykul and Ogres work maybe in the near future. I just want Rexxar as an Official Leader though...
