The Oran exchange shouldn't continue. Last time was kind of fine due to the absurd method to gain the pet, which REQUIRED many spins, thus, many surplus items.
In an instance like this where such a thing is not present, it seems like a waste that will discourage players from trading with each other extras to get what their 10 pull missed. There are better ways to have a potato sink that doesn't come at the cost of our wrists and our time.
