Use exotic double ups to infuse as much of your gear as you can. It helps. Also remember to always be at your highest possible light when decrypting engrams. And decrypt one at a time so if the new gear you got is better you can equip it and increase your chances of better loot for the next engram. I always try and do legendary/exotic engrams last as they're what I want the higher stats on. Hope this helped? Sorry if I'm telling you something you already know.
