After grinding a mere 7 days, encompassing over 40 hours of game play, I have accumulated enough common, rare, & legendary item engrams to level up my cryptarch from 1 to 14 (picture is of current crypt. level). Almost every single decrypted engram has yielded a rare item and I have only acquired uncommon/rare items (or shaders/materials,) from the postmaster upon each crypt. level gained. I estimate I have collected 200+ engrams and have only recieved 2 legendary items (out of 25 purple engrams). Does a man press on when the last legendary item he received was a gauntlet for another class over 13 purple engrams ago?
