Theory for Crotas End.

So with the last exotic patch we have these new Blade of Crota enemies. Upon killing them they drop a sword of Crota. Lots of us have already seen this mini event. My theory is that Bungie is training everyone for something in The Dark Below. I think that at some point (perhaps a strike or maybe even the raid) these Blade of Crota enemies will spawn. They will have tons of health and be pretty tough. I think we will need to kill them quickly to get them to drop their swords, and then we can pick it up and possibly use it for some purpose. The first thing that came to mind was possibly breaking Crota out of some kind of shield. Or maybe they will be really useful for tearing apart massive waves of thralls. Anyway, I think using these swords is going to be very important in the expansion. Just one guardians thoughts. See you guys in space, -Dell
