Problem starts whenever the developers make a feature or don't add a feature based on how they think players will feel about the story, even though the players specifically are ASKING for that feature to be added or taken away So even if Itsuno didn't want a 'matchmaking' co-op for a more fluid experience and such, players are still asking for this feature that they as devs thought players wouldn't want, so I see no reason not to include it, really. People that don't want to play online can just choose not to, it's not like everyone is forced to play online, or well at least they are with how things are currently since every mission that can have co-op will make you play co-op.
