With everyone believing Warlocks
Tailoring serves two purposes: one is crafting and the other is specialty cloth. Unluckily, Tailoring requires a few rare patterns. Without selling the specialty cloth, it is a very nice profit for a quick craft on tailors every four days. For Horde, it is worthwhile to pick up the Robes of Granado Espada vis. With everyone believing Warlocks are the be-all/end-all of OP solo ability; there are tons of alts that want to pick this item up to make their Bloodrobe.
