With all the things I'm waiting to hear about in patch 3.2, completely unforeseen news takes me by surprise. Bornakk just revealed that epic gems are coming in that patch, as well as some changes to other professions.
Jewelcrafters will be able to buy epic gem cut patterns with their Dalaran Jewelcrafter's Tokens. Raw epic gems will be available from prospecting Titanium Ore and alchemy transmutations, and will also be buyable with both honor and Emblems of Heroism.
Given that the availability of epic gems raises the value of the Blacksmithing perk (extra sockets), other professions are having their perks buffed. Details after the cut.
