3v3 (WoW)  

An Arena format that pits team of 3 players against each others, hence the name.

3v3 Team can have up to 6 players on the roster.

3v3 teams earn 88% of the points of a 5v5 team, making them less rewarding than 5v5, but more so then 2v2.

While many people claim that 3v3 is not as balance as 5v5, the majority of Arena Tournament (Including Blizzard's own) usually happen in this format.
