Who else would like to see armors fashioned around things like our enemies or places we go like mission specific? Say you could go through the mission to capture essence of crota and in said mission existed an armory cache with armors the hive recently developed to combat us directly? Same as any of the cabal missions? Not so much quest line material, but something simple like a patch on the shoulder for a particularly difficult lieutenant or minotaur or knight to show you completed such a trial? You could even extend this to our online profiles here on bungie.net. Past that, more sci-fi in general like weapons and actions in-game.
