In patch 1.11 we're implementing a non-consumable version of the Aqual Quintessence, available to players once they become revered with the Hydraxian Waterlords. This item will be available from Duke Hydraxis, and should allow the weekly Molten Core runs for many players to be slightly more convenient. ~ Eyonix

Raiders will be very happy and excited about this news! It seems that Blizzard is doing their best to ease the transfer from WOW now, to WOW with the expansion!
