I don't see any mention of a 2v2 format in the rules. Teams play against each other. Teams consist of individual players. Teams are formed based on skill after a random draw, separately for each of the formed brackets. The number of games each participant in each team plays is equal to the number of players multiplied by twice the number of players in each of the opposing teams.
The second question is about the ranked tournament, where can I see this current ranking? And will the ranking be awarded for all games in a pair, or only for the individual games you win?
