So, as the title says.. I've killed Atheon on hard mode about 5 times I can think of.. each time, I get Aspect of Glass, Mythoclast, and the raid helmet. One out of the 5 there was no helm, and another there was no Mythoclast, but thats close is enough. Is this really coincidence? 4 out of the 5 times I was using my Hunter with the exact same spec, but different weapons each time.
