The Glorious Conquest PvP quartermasters (Acon Deathwielder for the Horde and Ethan Natice for the Alliance) will be removed to refit the items that they sell before patch 5.3 arrives. Glorious Conquest PvP gear is being changed from item level 512 to item level 496, but this wasn’t a change that could be applied via a hotfix. In the meantime, we wanted to avoid a situation where players intending to purchase upgrades would buy these items, only to find that they had purchased cosmetic items when they are reduced to their new item levels with the arrival of patch 5.3.

You can read about the coming item changes in the PvP Gear in Patch 5.3 blog. See you on the battlefield!
