With flying coming to the new continents I'm thinking about farming world quests for disenchantables. Currently I have 9 world quests up that give items. If I did them all and they on average dropped 1 Veiled Crystal each that's 340g * 9 = 3060g.
Unlike many of my ideas this turns into actual gold reliably quickly. No need to place slow selling items up for months, Veiled Crystals are a busy market and if they don't sell on one listing they'll probably go on the next.
You would also get about 900 rep which is worth about 600g from paragon WR and gold payouts.
This could be repeated on every enchanter.
