I took up enchanting. Sure, its a huge money sink if you don't scan the AH for DE fodder, but as a mage, I'll be able to enchant my rings with +12 spell damage each, weapon with +40 damage, and my gloves with +20 damage. As a bonus, there were stretches of tailoring in which I was producing undesirable robes, so the best thing I could do with them was to DE them.
