Maldraxxus Duty Bound tint still not discovered

Hello, I’ve created this Topic as of means to hopefully discover the where abouts of the Necrolord covenant’s final tint set, the unity/Duty Bound set, it’s been rumored that it’s in the Duty-Bound treasure chest, however I’ve grinded that quest for the chest every week, and found only conduits and items sold for gold.

Found this in some comments over on WoWhead about it…

Yes. Correct. I just got Unity and when I asked Rathan about Unity. His reply: “Unity is a very unique construct. She is bound to the Shadowlands by an indomitable sense of duty, and is able to discover armor that symbolizes our purpose to the Shadowlands while completing tasks for the Undying Army in Maldraxxus.”"
