Tauren are actually from many different tribes:
Bloodhoof, Ragetotem, Dawnstrider, Runetotem, Highmountain (not the same as their Broken Isles counterpart), Skychaser, Thunderhorn, Cloudsong, Eagletalon, Mistrunner, Stonehoof, Wildmane, Winterhoof, Stonespire, Cliffwalker, Dawnchaser and Grimtotem (led by Jevan)
The same applies to the Highmountain Tauren, as they are Highmountain, Bloodtotem, Rivermane and Skyhorn
