So I searched on google for 'Crux of Crota' today, like I have been doing for the past few days, and I found an article which didn't seem to be getting the attention I thought it would. There is evidence, it has been dropped. Now I don't understand a word of what this guy's saying, but from the article I gathered that he dropped this on his FOURTH completion of hard mode. I don't know whether all three were on the same character or whether he releveled a character multiple times, or has three 32s and helped friends with another, as the article wasn't clear there. Repeated completions on the same character would explain the mysterious lack of drop for other players, though. It also has an attack value of 339, and the perks come filled out the moment you upgrade the gun. Just from the brief glimpse there...although it's running at 68% efficiency thanks to level disadvantage...it looks like shite. Reloading every two seconds, and it doesn't seem to work wonders on those acolytes, even. I hope it performs in Strikes and Crucible, otherwise the low drop will be pointless.
