One of the more awaited cosmetic appearances coming in Patch 10.0.5 are the datamined Sun and Moon Night Elf Warden transmogs. When we originally reported on these transmog appearances, there were no discernable sources to obtain the transmogs.
On the most recent Patch 10.0.5 PTR build, a new ensemble with a Warden helm icon and a name that does match a Warden armor has been added – Ensemble: Burden of Unrelenting Justice.
