An Arena match format that pits teams of 2 players against each other ("2 players Vs. 2 players" = "2v2").
2v2 Team may have up to 4 players on the roster.
2v2 teams earn 76% of the points of a 5v5 team, making them the lowest Arena Point gain of the 3 available team formats. However, due to the ease of organization involved in having only 2 people to get together, it is also the most popular format.
It is often considered the least balanced of the 3 formats, since class composition can make for extremely one-sided battles.
