If you're looking to level up your crafting, I'm clearing my ingred bag of ~40,000 lesser essences - 1.6M pp or trade.
All types, heavier in elemental/divine. They're up on the AH right now at a higher price, so I can't guarantee they'll all be available. After one round on the AH, I'll probably be willing to sell individual stacks.
Forum PM gets my attention the quickest since they fixed email notification.
