So far I have logged 67 hours in Destiny. Most time spent in story mode, strikes & 3 runs thru the Raid. I've kept up with legendary engram drops just because I knew how rare they were gonna be. I didn't realize how rare. To this day I have had (1) legendary engram drop from a strike enemy & (1) legendary engram as a reward for the daily mission. Yup, just two, the first one luckily gave me legendary sniper, the second gave me shards.
