Should matchmaking be an option for those who can't get people to play with? People have things to do. There isn't always the option of playing with friends for multiple reasons, such as weird job hours, lack of friends who own the game, family, etc. I personally think that you should at least be given the OPTION to use matchmaking. This could not possibly hurt the game, and it could even provide an extra challenge by playing with random people because there might be a lack of communication, for those who seek it. Let's face it- if one was really in this scenario, I doubt you would be going into battle with a best friend. Either way, matchmaking can provide a great way for people to complete things that otherwise not be available to them. It's better than not being able to do them at all. Everyone should be able to play a gametype, regardless.
