Well, it's not the Cryptarch directly, but rather Kadi, the postmaster. My brother, since before the patch, had been raising his Cryptarch Rank, like I have. We had acquired the occasional Legendary engram from Kadi upon Ranking up. However, ever since the patch to the Cryptarch, I have been getting only Rare engrams. My brother has now been getting 1-2 Legendary Engrams with EVERY Cryptarch Rank. This has happened since the patch, when I was Cryptarch Rank 31; I'm now 49. For all those Ranks I have acquired nothing but Rare Engrams, whereas my brother, Rank 29 at the time, has been getting 1-2 Legendary Engrams with every Rank up, with an Exotic Engram upon reaching Rank 45. Is the Cryptarch system still broken? Are Kadi's rewards randomized? I honestly have no clue. I have raised myself 18 Ranks and nothing but Rares. My brother has done the same, but has raised his higher than mine, and have acquired a bunch of Legendaries and one Exotic. I just want to know what's up.
