if hats are "useless" than why have the sethat npc at all? its an item to customize your character further and it would help the economy in the ways you mentioned yourself...

A trading card game on a video game is pretty dumb IMO. If I wanted to trade cards, I'd go trade cards IRL. You say hats are useless but so is a trading card game lol. I've loved card games too but why on graal? I want something that can customize my char more. As far as cards go, hats are comparable, they can be traded and collected, so its basically the same thing, just a hat economy would probably appeal a lot more to the rest of graal.
