I’m wondering if that is what they actually intend to do. My Hunter can mog the mask now that it is cosmetic (great change), but if she attempts to equip the Vile Fumigator’s Mask that she has then she is told she needs a target. Okay, go target a training dummy … then she sees this message:
So either they have completely stopped the ability to /use the Mask to attack OR they now require the back piece in order to do so.
Oddly enough, on the PTR I could still equip the Mask and get the full outfit. That option never made it to live.
