I'm sorry, but I disagree. This is a game designed around the concept of co-op play. You are asking them to change the whole development idea, when they already did that. Some of that list sounds like Halo on legendary difficulty and the mythic skull on. This isn't supposed to be a solo focused game. Even as I say that, I do have to admit that I have played most of my time solo, but I do enjoy teaming up. I would rather see Bungie spend their time on polishing this game and developing more unique content for it than shifting their focus. But then again, that is just one guardian's opinion. :)
