Oh my god.
The supply is limited because its not infinite.
Dude. Go learn basic econimics, this is ridiculous.
Buying goods from a vendor is infinite supply. You can buy endless items from the vendor if you have endless gold.
You cqn not do that with stuff in the AH, there is an average that is supplied to the market each day, it can fluxuate, but its limited in that at any given point a person could buy 100% of the market and there would be no more materials (until eventually someone listed some).
The demand on low pop servers is high since there’s not much supply, which means cost of mats is high.
So when you merge that market with the market where cost of materials is low because there is high supply, there is a disparity that gets filled higher. Average price goes UP not DOWN.
its irrelevant if its a low pop server or not, if the price is 60% higher and that market is only 30% in size of the full pop server, the AVERAGE PRICE still goes UP 18%. How are you struggling with this?
