Has anyone actually managed to sell any of the AF2 gear?

How are you making them? All self gathered, or are you supplementing with mats from the MB?

Self-gathered. I was listing the favor mat sale prices as a reference point for the economy. I've personally had 4 Ooids sell for 1 mil each, but I'd say 250-500k is the norm.

I can't imagine who would buy a ring for 10m. The material cost isnt anywhere close to that, at all.

Even with the favor materials as they are, 10m is way overpriced for a ring, as rings only take 1 material to craft. That effectively makes their price value only slightly above that of a single HQ material. (1.5~ orso over that)
So unless favor materials add up to being like 8-9m for one crafting material, rings shouldnt sell for 10m.

Favor Mats: 250-500k each (5-10 mil based on price)
Leafborne: 500k NQ (1-1.5 mil HQ if you can find them)
Fieldcraft 3: Trivial
Varnish/Clusters: Trivial

If you purchase HQ sands and all the favor mats at their cheapest price you get 6 mil. Getting a 1.5 mil profit (I'm assuming that is what you mean by 1.5 over the material cost) on something this time consuming and high risk is absurd. An off hand would be approximately 3 times the value of the ring, or ~18 mil gil to craft. You may as well keep the item if you are going to sell it for a 2 mil profit.
