In a surprise announcement today — well, maybe we should've expect this — Bungie outlined a new patch for Destiny slated to go live next week. Patch 1.0.2 includes several changes to the Cryptarch and Engram experience that will hopefully improve the overall loot system in Destiny. On the most basic level, these changes will guarantee that Engrams will always decode into items at or above the quality of engram. That change alone should help alleviate much of the problem.
Here are the changes planned for patch 1.0.2, arriving next week:
Cryptarch Changes 
Cayde-6 took the Cryptarch aside and showed him a sack of doorknobs. He decoded that mystery pretty quickly.
- Legendary Engrams will always produce Legendary or better quality items, including Materials or Exotics
- Rare Engrams will always produce Rare or better quality items
- Rare engrams will have an increased chance to produce Legendary quality items
Activity Changes
- Daily Heroics, Weekly Heroics, and Vanguard: Tiger Playlist activities will include Rare and Legendary Engrams in addition to their existing rewards
Item Changes
- Ascendant materials have been promoted to Legendary to closer associate them with the gear they are used to upgrade
- Legendary Engram items that exist in your inventory will be demoted to Rare quality when the patch goes live, so decode them while you can. But let’s be honest–even if you don’t, we all know they were blues already…
Unfortunately, only Engrams that drop after patch 1.0.2 are subject to this change.
