It's an item in the game that's tradeable (by which I mean food that goes on plates).
Classic has never had that before. So it's become a bit of a niche market. There's always players who are obsessed with collecting anything and everything, and then there's players who are market-savy and figure out creative ways to make some gralats. I personally don't take part in this, but I like being able to give food to other players. Makes for good prizes for contests or player-made events (which I love to do).
Doesn't need to be changed or "improved upon" in any way.
