50% my ass. I ran 40+ heroic strikes this weekend and got ZERO exotic engrams. Actually, I haven't seen an exotic engram since CoO released. Only exotics I've seen were from powerful gear and the story exotic. Fix your F*CKING game already. Oh right, you're too busy worrying about that sh*tty comic you just released, which is garbage. Worry about the game for a change, and what your player base wants.
