Is there anywhere I can buy 90 gear from seeing as how I'm in all my T13 gear, lol.
I'll prob just buy honor gear with the points I've been racking up. But what about PvE specific gear?
You buy JP and VP gear from the various Pandaria faction Quartermasters, or the JP/VP vendors at the Temple of Niuzao in Townlong Steppes. The honor gear is at your faction's PvP vendor hub in Pandaria. They're both on the Serpent Spine (the big wall blocking off the Dread Wastes), the Alliance one is south of the Gate of the Setting Sun and the Horde one is north of it. If you're level 90 they'll be marked on your map.
