So as we all know, greens/blues will be so expensive that the amount of mats you'll get from disenchanting them makes it the same amount of cash spent.
What most people DONT KNOW, even addons like auctionator, is that BoE relics dropped from mobs can be disenchanted.
Why is this useful information? Because as many people don't know this, they usually go for 25-50% lower than the cheapest greenies, meaning huge profits if disenchanting! You can even buy through trade chat, because people do not know that this can be done
