1. 1 round - first pairs will be randomize by league system (simultaneously randomizing groups), after 1st round independent of battle result no one leaves tournament.
2. 2 round - winners of the first round in their groups plays with each other for better position in next round, loosers of the first round in their groups play with each other for standing in tournament (loose means end of competitions for these players). Player who won 2 rounds has 1st place and don't need to fight in 3rd round, just wait for 2nd stage (2 weeks break).
3. 3 round - only for players that already has 1/1 (won/lost). Last chanse for 2nd stage, winners promote, loosers are out of tournament.
кароче это как группы, только в конце перое место не играет с последним и сразу выходит в следующий раунд.
