They say:[quote]We speculated that you may have needed to do something specific, and it looks like you just need to keep completing Crota’s End on hard mode – one time isn’t enough. Simply defeat Crota more than once, and you’ll have the chance at acquiring the Crux of Crota.[/quote]They specify:[quote]With the Crux of Crota, they’re likely tracking who has the Glowhoo shader (a guaranteed drop from Crota on hard mode), and if you don’t already have the shader, the Crux has a 0% chance to drop for you.[/quote]What do you guys think of this theory?

We now know that the crux cannot be obtained on your guardian's first Crota kill, but on any after the first. I myself got in on my 2nd Crota kill.
