I have noticed since the 1.1.1 patch that Legendary Engrams only give Ascendant Shards when your decode them and Decoherent Engrams drop way less in Strikes. I used to get like 15 from 3 strikes, now Im lucky if I get 10 from 9 Strikes. I also noticed March 3rd everyone was getting Exotic Drops that day, and that could be a bad glitch if you only get Exotics the day of the reset. Don't get me wrong, 1 of my 2 drops was absolutely amazing but still, not worth the tradeoff.
