Ever since I installed the update I haven't come across a single Blade of Crota. Normally they spawn often but I simply can't find them. No messages broadcasted saying the Minions of Crota have started a ritual or saying the Blades of Crota have invaded this world. They're simply gone. For me at least. Is this a bug? Are you experiencing this problem? Are they doing this to ease us out of The Dark Below and into The House of Wolves? I've always loved these small aspects of destiny and I really hope they didn't take them out of the game.
