Here's the current issue I have seen a lot of people get stuck with including myself. An abundance of aqua!! Now my idea to remedy this would be simple. At the beginning of each eb you could select which of the two you need (only aqua and inferno) so that you would only get what you need. But at a cost. So here's an example Say you have heaps of aqua (70 or more) and you need inferno. So you join a clan running something that drops it. So before hitting the eb you pay 15b to ensure that if you get the drop you get the element you need more of. I see this as a useful addition and also a gamble. But there days 15b is nothing so it's not a big loss if you don't get it.
This whole idea is stupid Op no bad op If you want inferno that much you buy it using your eb fairy gold
I think we should be able to trade aqua for inferno an inferno for aqua. (That gif up there nearly made me spew too) -EA
