Personally, I very much prefer 4 person teams. It adds teamwork and makes the game more competitive. In Call of Duty, all I play is Team Tactical because it has 4 person teams and it’s a lot more fun compared to the 6 person teams where no one talks.
I really hate though that they’re getting rid of all the small maps. Maps like guardian and lockout were the most fun and they could be played 4v4.
