And tell me how exactly is Paramarket supposed to help you with a bot ridden server that will easily adjust it's pricing to still come out on top above of Paramarket?
Literally the only reason I've seen that holds any ground of being a valid reason for the thing existing is on Chaos is the fact Paramarket offers HP% restoration consumables that can't be obtained through other means beyond seasonal events.
The system itself does nothing to stop bots, or deflate the zeny economy.
