Junk trading only exists because the Grand Exchange is out of tune with player prices, as player prices fluctuate wildy and it can't cope with this. To eliminate junk trading all Jagex would have to do is make the prices update more frequently on static items and let US decide the prices of new items. I don't know if anyone remembers but Jagex said they'd let us decide the price of new items, this was a blatant lie. The new animal masks are hardly going up at all because people see the prices that the players are paying, they compare it with the Exchange price and they are being forced to not sell on there as they don't want to rip themselves off. If Jagex is getting rid of junk and not allowing the prices to reach the proper player prices, then they're screwed basically.
