I wouldn't mind Starfire Protocol or Heart of Praxic. I have yet to see those drop for me since day 1, but I'd be equally happy for a chest engram to roll the dice and level up my Craptarch. Weapon wise, it doesn't matter. G-horn would be nice so more people have it, even if I already do. The more the merrier I'd say. Personally I'd love it if he started selling weapon engrams.
