I don't understand why a buyer would like FF11 AH, it was good for sellers only,
buyers need to test the price from low to high for many many times or you will over-paid for the item.

Moreover, in FF11 crafting not really make profit, actually the profit was came from the materials, unless you got a HQ by RNG.
And I recall during levelup crafter, I needed to sell all products to npc as no one will buy,
and I even needed to camp at the vendor npc to buy the materials upon daily reset.

In short, IMO economy in ARR is more enjoyable than XI ^^;
