So you should expect to keep your hands on the fang of ir Yût, vision of confluence and your deathsingers mantle that are completely useless just because you "earned" it? You can very easily run right back through Crota with a buddy or two, get it all back and it wouldn't be any different than the stuff you broke down. Either stop complaining you don't have vault space when you insist on keeping junk items, or stop grinding one activity for hours when you k ow you fill your post master in half an hour
