Why would you want to trade your credits for clintz. You can save up 20 clintz and buy a pack of cards and sell the cards in the pack for 3000-100000 depending on what you get. I bought a new blood pack and got Elya splata and i dont remember the other. I sold all three cards and made 70000 clintz as to where you would only get 2000 clintz. Rare example but you almost always make more money by buying packs. TRust me they did you a favor by removing that option.
