just found this on MMO champ [URL="http://us.battle.net/wow/en/forum/topic/6759237078?page=1#1"]source (US)[/URL]
We've just applied a hotfix that removes the faction requirements for Justice gear.
Shado-Pan and August Celestial factions will no longer require Golden Lotus faction to purchase this gear. This will allow players who have reached level 90 to have additional sources of item level (ilevel) 450 gear to progress into the Dungeon Finder Heroic dungeons more readily.
Players who are looking to purchase this gear should seek out the following vendors:
Shadow-Pan - Rushin the Fox in Shado-Pan Garrison
All - Commander Lo Ping in Niuzao Temple
Vale of Eternal Blossoms:
August Celestials - Sage Lotusbloom or Sage Whiteheart in the Horde and Alliance Shrines
Golden Lotus - Jaluu the Generous in front of Mogu’shan Palace
Klaxxi - Ambersmith Zikk in Klaxxivess
this was on the US forums but I'm assuming it will go live on the EU servers tomorrow.
