This has probably been suggested a lot, but I just got the Vanir armor set and it was such a bittersweet feeling. Although the armor set looks so damn great, its not very useful to me as a level 34 titan. I hope Destiny gives us a way to upgrade pre-Taken King armor or Transmorg it at least. After watching The Taken King videos, I saw armor and weapons that are uncommon/rare for higher levels, so it would be cool if you could upgrade rares to higher levels, or have certain armor sets like the PS Exclusives have 2.0 versions for when they're released on Xbox.
