Aqua and inferno have been imbalanced a lot, with people getting more aqua or more inferno, I have 64 aqua and no inferno while a friend has 28 inferno an no aqua. Other ideas have been made, but have the problem with growing lays extremely quickly. The flaw was you trade with other people, but here you trade with yourself. I propose that every day you may trade a certain amount of aqua or inferno for the other, maybe ten per day. Sorry about the good grammar, but the grammar nazis are invading.
