Several MoP Beta builds ago, the hunter armor sets previously labeled as PvP and Challenge Mode were swapped. What was formerly said to be the PvP set is now the challenge mode set and vice versa. The image above and the video below show the new Hunter Challenge mode set. This is the cosmetic transmogrification set that’s rewarded for successful completion of all 5-man dungeons in Challenge Mode: Gold for the achievement Challenge Conquerer: Gold. For full size images see the female and male sets at MMO Champion.
