I quite like the teams of 2. I think it allows for more individual play and you don't have the ability to solely rely upon having a huge team to back you up. It also allows you to not have to be near 3 players for your compass to track other teams/players. If it was an option to choose between 2 or 4, then teams would be unbalanced, as players who have a team of 4 would have a huge advantage over those who choose to play as a team of 2. Before someone replies with the counter argument that it's their choice, it's not like they have much of a choice is it. They either play with a disadvantage or they play with a team of 4. No one really wants to play at a disadvantage so they're may as well not be a choice. At the end of the day, I guess its personal preference, but I'm all for teams of 2.
