Last weekend, my fire team and I attempted the Oryx Challenge Mode on normal, and the 16 bomb strategy, the only one that should work, didn't. We detonated all 16 bombs at the same time (and have a screenshot to prove it). Oryx shook it off like a couple of BBs. We called it quits shortly after. Then, last night, my fire team and I attempted the Warpriest on Challenge Mode. It took a few tries, but we finally managed to defeat the Warpreist. However, when we collected our loot, there was no chest, and only one of us got a 320 weapon (Harrowed Defiance of Yasmin), one got a 306 Defiance of Yasmin, and 4 just got moldering shards. None of us had done the raid since the reset. We were under the impression that everyone was supposed to get a 320 weapon from completing it. Any help?
