Well, that's a surprise.
The orbs will still form a part of crafting as they're listed as mats for a number of 4.3 patterns, but their availability means that they're going to lose value very fast. I know I'm not alone having two full stacks of 20 orbs sitting in my bank, and I can only assume we'll see a positive flood of 'free' orbs once the patch drops.
Next question: will Trugold be coming off cooldown?
