There’s also a recolored version, which may be a hint that this set could make its way to the Trading Post?
Although this looks to be a simple update to the existing Ironforge Guard NPCs roaming around Dun Morogh, or perhaps a hint that we’ll see a group of guards engaged elsewhere in the Dragon Isles, that may not be the whole story. The axe, shield, and tabard all have associated tooltip icons, which is unusual for NPC equipment, suggesting that there could be player versions available at some point.
It’s also worth noting that the Dwarf guards don’t actually wear their tabard either, so at least that item seems likely to be obtainable by players at some point. While near identical to the Ironforge Tabard from Wrath of the Lich King, the aging appearance has been in dire need of an HD update!
