One of the most interesting functions of Fix 5. http://www.arm2teeth.com/ is the capability to upgrade your items with justice and valor factors (as well as improving PvP items with respect and cure points) and to be able to offer you a feeling of what the existing condition of this function is on the PTR, I went looking for the upgrade source. They're not nearly impossible to discover -- look for the ethereals who do transmogrification and reforging, and you'll discover them standing in the same places. I verified this by going to Orgrimmar and the Shrine of Seven Celebrities, and there they were.
Since I was on a pre-made personality with no respect or cure equipment and no epics, I could only test the justice factor interface. Still, it's value looking at how the procedure performs. As you can see from the above screen shot, the existing interface will look acquainted if you've reforged your equipment at any factor. But there are some variations.
