Why did I even bother grinding for each season's Iron Banner Ornament set? Why are three sets of raid armor per class not being used? Why can't we enjoy Y2 while being able to wear the things we earned in Y1? And yes, before you ask, technically you can, but without any armor perks, putting you at a huge disadvantage. We should be able to transmogrify an Armor piece onto a Y2 armor piece and keep its perks, but change its appearance. It's not that hard, games like Injustice 2 pull this off easily, and still includes tons of grinding and microtransactions.
