From my perspective, this shouldn't justify the complete removal of persistent lobbies and their unmeasured benefits, even if it's just persistent for a handful of matches like BO7 used to handle it in normal modes. Persistent Lobbies: - Allow for a feeling of playing in a social environment against real people so there's no sense of community or ability to form friendships and rivalries. Why care who I'm playing with/against if it's guaranteed to disband? - Help create more of a "story" of a session where there's back and forth and your previous nemesis maybe ends up on your team and you mesh well together or you have rematch after rematch while being able to learn player behavior and adapt to them across matches if they decide to stay - Help keep a generally consistent pace of a session as well with clearly defined breaks between matches instead of instantly being thrown into another match - Can help keep some consistency with map rotation (when handled properly) - Allow you to stick with a good connection lobby for multiple games instead of being bounced all over from one side of the continent to the next like I very often seem to experience If people want to leave, then they should be able to do that with no issue but by forcing lobbies to disband after every match, you remove player agency and create a disjointed, anti-social experience which harms the player experience for many and yet, these negative effects likely don't show up in the specific metrics that are being tracked here. Call of Duty used to be all about community but it seems a lot of that has been thrown away in the pursuit of optimizing certain metrics. I thought the BO7 system was at least a decent compromise as it allowed a solid chance of a lobby sticking together, even though it would disband eventually. Either way, there has to be a better solution than just removing persistent lobbies and all of those potential benefits entirely.
