Reforging on 4.0.1 PTRs
We've been creating a lot of builds lately for 4.0.1 and Cataclysm beta, so Reforging NPCs may not yet be available. As with all PTR processes, the patch notes are not comprehensive. Some changes may not be reflected in the notes, while others may not yet be available in the current build.
If Reforging is not yet active, it should be in an upcoming build. We want to give players a chance to try out the new feature. With all of the class changes going in, Reforging will allow players the opportunity to customize their gear a bit more before Cataclysm actually ships. It will also allow you to add Mastery to existing items if you so choose. ]
