That's weird. On my server the prices on epic gems are so low that most average players have a ton of them. In my guild that is an average raiding guild, I can promise you that it won't be 3-4 months before we have all epic gems.
Anyways, I can't help but wonder why they rolled back the buff on JC on the PTR in the first place. What made them think, that buffing BS as a result of the new epic gems without buffing any of the other professions (in particular JC) is okay?
