Got a legendary engram from leveling up the Cryptarch. Turned out to be a heavy weapon engram. I was a level 26 who still owned a rare rocket launcher because RNG hates me. So, I got really excited. I looked at it before I decrypted it and was so excited to see what I would get. I pressed 'A'... And got two ascendent shards. I was so pissed... RNG continues to hate me with heavy weapons to this day. I was forced to buy a rocket launcher from the vanguard and then I had to buy Truth last week from Xur. Haven't gotten a heavy weapon legendary engram or any heavy weapon drops since.
