So I know someone already posted about this, but this is an update, sorta... I'm not sure if anyone has pointed this out yet, but these skins:

Which people believed had one of three purposes. The first was the new Sunwalker (Tauren Paladins) specific skins (which is unlikely, since the only class with unique skins was Death Knights), new tauren warpaint cosmetic (which was also unlikely because the paint was only with one skin color), and the final was a new NPC skin for Grimtotems.
Well last night while turning in the shield quest that you get in Dalaran and turn in at Thunderbluff, I clicked on the Grimtotem body guards, I was about to leave when I noticed their icons looked a little strange, so I investigated and this is what I found.
Now, this doesn't 100% confirm the fact that it is only an NPC skin, but it shows a high chance. (Atleast in my opinion)
