I've been having issues getting enough Armor Material that I tend to lose gear I don't want to because I need to upgrade another armor for a Mission or Crucible. After talking to some people on this forum. We wondered if we could use Motes of Light & Legendary Marks to upgrade things like: Ghost's, Gauntlet's, Armor, Titan/Warlock/Hunter Marks, Helmets, etc that would other wise be so low with both Light & Skill level that your better off deleting it then keeping it over time. Then players could keep the items they like the most then always mix matching things they don't. Hope this helps with "we're working on that"!
