Compared to all other crafting skills, Jewellery Crafting (or rather, Jewelry Crafting) is the only skill that requires 10x the amount of materials to upgrade. For example, making a legendary upgrade, would take 10 grains 8 times, meaning 80 grains, which at least on PC NA, is between 720.000 to 800.000 gold for One Single Piece of Jewellery. Imagine if any of the other crafting skills required that much. Another comparison is that, if you had 100% chance to retrieve one grain from deconstructing a legendary jewellery piece (which you don't, as it's closer to 50% or 75%) it would take 80 unique legendary jewellery pieces to have enough grains to upgrade a jewellery piece once. The refining of raw materials also seems to rarely give grains, compared to other crafting skills.
So, the question I have, is why on earth would ZOS ever design something so moronically? It's not as if golding out a piece of gear buffs much besides traits, so you can hardly argue that it's worth upgrading jewellery to legendary for the exorbitant cost required. Is this just meant to artificially inflate the content, to ensure players grind until they grow tired of the game? If someone at ZOS could honestly explain what the thought-process behind this was, that'd be appreciated.
