We’ve revised the Justice Points conversion rate for Emblems of Triumph and Emblems of Frost. When the upcoming 4.0.1 patch goes live, these emblems will be converted into 11.58 Justice Points (up from the previously planned 2.75 Justice Points per emblem). Justice Points accrued above the soft cap of 4,000 will be converted to gold at a rate of 47.5 silver per point (down from 2 gold per point) when patch 4.0.3 goes live.
The original explanation thread (http://forums.worldofwarcraft.com/thread.html?topicId=26850245012
) and the subsequent conversion math update (http://forums.worldofwarcraft.com/thread.html?topicId=26850245012&sid=1&pageNo=10#184
) have been updated to reflect these changes.
