Sometimes, I don't want to play Attackers and play Defenders, and when I don't want to play Defenders I want to play Attackers. When I press Tab I can see what members compose each team as well as how many players they have.
In some instances, I can clearly tell the other team has 2 or 1 less players than our team. If I want to switch teams to join the other team, how can I do that?
