1. Market forces. Twenty years ago, NO ONE had fast Internet, because it wasn’t technologically possible. 2. Low player numbers. Which is the problem Bungie is dealing with right now. As this games players are spread out across a half dozen platforms. 3. For the same reason you have people arguing for CBMM? Or why there is a video about people abusing Steam’s refund policy to get a refund on a game after they played the whole game. Some people are selfish, and don’t play well with others.
