I've hoarded a nice amount of engrams 2 Exotic and 2 Legendary Primaries 3 exotic and 4 Legendary Secondaries 4 Exotic and 1 Legendary Heavies 6 Exotic and 14 Legendary Arms 6 Exotic and 11 Legendary Boots 2 Exotic and 1 Legendary Helmets 1 Exotic and 10 Legendary Chests and finally 5 Legendary Class items In case people are wondering what might have a higher drop rate. it appears arms and boots are up there. Especially boots. They're the only Legendary engram i would decrypt time to time if i had no space since i started i think i decrypted around 6. and 8 class items, but who cares about those.
