Destiny DLC. That's not editorializing; that's a takeaway from a post that designer Luke Smith made regarding mistakes that will not be repeated for the game's second bit of downloaded content, House of Wolves. Smith explains the shard economy essentially functioned as a barrier to prevent people from actually equipping their shiny new pieces of kit, thus invalidating and minimizing the effort put forth by players.
Ultimately the goal is to make reaching level 32 with gear easier while giving players more incentive to keep tweaking their setup via new upgrades and better traits on items. Smith also states that the economy is not going to be adjusted this tier simply to ensure that the people who have already put this much work in will not find themselves invalidated again. It's a change to be made moving forward, one that will hopefully improve everyone's experience in the game once the second DLC update drops.
