'People would not post crazy prices if no one was willing to pay them.'
That simply isnt true, you cant expect everyone to know enough about the market value of an item to always post it for a price that anyone would buy.
‘If every single person were to lower their prices on realmeye today to market price, in a week, a different set of people would have raised their prices to take advantage of the currently existing buyers that are willing to overpay. So long as people are willing to overpay, there will be people posting offers for crazy prices.’
Agreed, and thats inevitable in a free market, but I dont feel like contributing to that problem. I dont think that every trade with another player should create profit, thats what dungeons are for.
