官方人员在Q&A里有这么回复过:For questions 1 and 2, I think it falls into a fuzzy story area right now, where the events of the Co-op missions are supposed to be taking place during Amon's invasion of the galaxy. So it kind of happens in parallel with the events of Legacy of the Void. That said, we don't consider anything that happens in Co-op canonical, to allow us to be a little wacky with the theme and gameplay. So you might end up seeing some other opponents in the future, but shouldn't consider it the official storyline.
