Again, what kind of dedicated crafter doesn't even level sub-classes to 15? It literally takes 45 minutes, and dramatically increases your HQ odds.
More examples of price silliness: Selling pairs of Vanya Breeches for 555,555. Vanya Breeches require 18 Potash, which sell for around 33k each, so 594,000 not counting other mats/clusters. Every other pair that has sold went for 1.5m+. This isn't something a "dedicated crafter" does. It's something an RMT does to generate gil.
It's as if he lists items while ignoring their cost, something that wouldn't make sense for an actual crafter to do, especially when there's no one else selling the items and they have a history of selling.
How does any of this explain selling multiple items for 555,555 when the mats cost 600k+ and the only history for the items have them selling for 1m+? He instantly posted items for every recipe he could make and, on the same day he hit 50 GSM according to his Lodestone, posted these dramatically underpriced items for every GSM recipe.
I'm a little baffled by some people here trying to explain this away. If you know anything about the games crafting system, you'd know it's almost impossible to come up with the mats he did so quickly (especially with no history of buying subcomponents) and any type of "guild" crafting idea again makes no sense considering how under-leveled his other crafting professions are.
RMT like this is going to destroy any type of crafting market that still exists if something doesn't get done.
