Spent all my shards on 3oC expecting more drops. Played for 3 days each time with a 4 hr window with 3oC active. Got one exotic every time from pubs, strikes, crucible - 4 h window. I am pretty sure i would have gotten the same rate whether or not 3oC was active. Like the guy below me says - so its 15% now instead of 10%? I dont understand why stacking wasn't an option like D1
