Tauren ideas?
Tauren with big-ass scythe, to chop Centaur legs off in battle
Tauren with big horns, attachment points on those horns, and a set of simplistic corpse attachments of different races - i.e. enemies he impales on his horns
Unarmored Tauren with massive helmet, humanoid Stand and Walk animation, but Wolf's Walk Fast, Ready, and Attack animations - i.e. a savage, who runs on all four (as a nod to their Plainsrunning from WoW Alpha), rams enemies with his head and mauls them with his fists.
Defensive structure that is a big Barrens stone pillar with another rock balanced on top, surrounded by ropes. Attack animation drops the rock and destroys the pillar in explosion of dust (basically, a heavy-duty land mine)
