is there actually an original Baine model?
unfortunatly no. Even when we select the reforged baine model we get the spirit walker.
I used the Tauren Chieftain because he is very closed to Baine original tauren model.
I wanted him to look like his original wow model because it was more bad ass
I will try to see if I can also make a model similar to the new model in wow. But I am no
@vindorei 
I also really love how the default model for tauren chieftain looks. He also uses the axe that old baine was using in the cataclysm dungean
Dungean boss baine
