I just downloaded a windows macro recorder to click the Cannith greater essence sundering button for me.
I can't even begin to express how much it bothers me that I just had to do that to sunder the number of essences I have.
I don't level up crafting all that often because you need a rediculous number of essences to do the higher level crafting, so I save up. With just one greater essence split per click, that's a LOT of clicking.
Please add a recipe for sundering 10 Greater Essences into 50 Lesser Essences.
