I think the Prismatic Recaster with Umbral Focusing is a good way to reduce repeated drops of an unwanted item. And the Recaster stays all season, why not apply some of that to Iron banner rewards when its only around for a limited time. The basic idea is that you can choose to redeem Iron Banner Tokens for either a weapons engram or armor engram. And you don't have to stoop there, the more options for players the better! Thank you
