I think that aqua and inferno should be able to be traded in user game play. This would help so many people, because people are getting like hundreds of aqua or inferno without getting a single of the opposite. The trading options should only be 1 for 1, 2 for 2, and 3 for 3, and so on. This way of trading would also prevent people just farming the aqua or inferno? support? I don't know, i think this would help so many people out that only have the one type of enchanting materials. In trading for this both players must be present at trading time and they both must agree on the deal. I think this can be done in the Mage.
