Beat Oryx with 20+ moldering shards and all I got for rewards were 2 moldering shards. That's crap. You took 20 from me for better rewards and didn't even give me a weapon. You gave 2 moldering shards. So my reward for beating the hardest boss in destiny was negative 18 moldering shards. Thanks Bungie! Edit: Ok, so some of you are saying that it's RNG and other raids have only given you materials. Yes, this is true. However, when have you ever beaten a boss and after had less than what you started with. Taking 20 shards and only getting the guaranteed 2 from beating him is a broken mechanic.
