When you run heroics now the bosses drop BoP, Unique on Equip Epic Gems. Next Patch they WILL NOT BE UNIQUE! So start stocking up on them now because everyone is going to be rolling on the when it comes out. the +11 healing ones are exp good.
Hope this helps :P
(didnt check if someone posted this b4 but i read the what to stock up on pre 2.4 and didnt see this so i thought id make a thread)
