One of the most controversial decisions in Mists of Pandaria
was the idea of putting JP and VP gear behind reputation gates, making you grind to honored with specific factions depending on what you wanted to buy. Blizzard has just put a hotfix in place that removes this requirement for justice point gear. You can now visit quartermasters as soon as you like and buy whatever JP gear you can afford, regardless of your reputation. This should allow new level 90 characters to hop into heroic dungeons much more readily.
The full announcement is behind the break, along with a quick guide to finding the reputation quartermasters to grab your gear. You can also visit Commander Lo Ping
at Niuzao Temple to buy all JP gear at once.
