So I was doing some story missions and I got 2 legendary engrams drop for me (2 different missions, but same day) then I level my cryptarch up and got another 2 legendary engrams from it and I NEVER (have done once previously) get legendary engrams when in PvE story/patrol. The new patch just dropped and there was nothing about engrams so I was wondering if anyone has had this or have I just been super lucky? Remember this was in one day, in the space of about 3 hours.
