Highmountain tauren did't have moonkin update from time there were released, get late update now with these patch of time gating.
I read Stag antler as Stantler.
They do nothing for regular boomkin form, how many years has it been? Since we are pretty much forced to go into boomkin form, at least they can make it look awesome, typical blizzard, lazy af.
With all this, I'm beginning to wonder what the armor for the Kul Tiran crow- "cough!" boomkin form will look like.
