Do Activities Instead of Hoarding Engrams
Once you hit 350, the leveling process will slow to a crawl. This is because your Legendary and Exotic engrams will now have a 50% chance of giving you items that are only one point higher than your current level. This means that mass decrypting all of your stored up engrams is definitely not an efficient way of getting over that 350 hurdle and pushing you towards 365.
Instead of hoarding engrams and decrypting all of them in one go, consider doing the other activities available in Rise of Iron instead. The Strike playlists (both normal and Heroic), the daily Heroic mission, and the new Archon’s Forge challenge arena are all great ways for grinding up those levels and obtaining more valuable loot. You can also head back to the Challenge of Elders, as Variks will now reward you with higher light level items as well. If your level is high enough, you can also consider tackling the Nightfall mission, though I advise bringing in a fireteam, as these missions tend to be pretty brutal.
