Would love, love, love to see one of the vendors or kiosks offer a Chroma Exchange. It is hard as all hell to complete a set with all one color and I find myself with tons each of my unwanted colors. A fair exchange rate I think would be 3 for 1, which just drops another random color which was NOT used in the exchange. This would make it so you can only do it so many times and are still not guaranteed you will get the color you seek, which then also makes it so that neither grinding for nor purchasing the boxes becomes obsolete. Please consider!
