I don't think Jagex do care about the prices of Rares going up. Why? As a matter of fact some people stay on RS more then they should to make more cash just to buy rares, so they can be statisfied. Rares will just keep sky rocketing, and as Jagex introduce hard new items to obtain, this will influence the rares. Imagine Dragon Plate releasing, and very hard to obtain. People will try to sell for the prices of the most expensive rares - Blue Phat. But then merchanters or anyone who owns a Blue will increase the price in-demand and over time the Dragon Plate will decrese and stablized, while the Blue will increase. I completely gave up getting any Phats, not to mention time spent to get it, not worth it anymore. Prices just keep sky rocketing while im trying hard to earn cash :?
