So each team can pick 1 HardRock, 1 Hidden and 1 DoubleTime map during match.The rule changed? It shouldn't be only 1 mod for each team at group stage(2 for each team at knock-out stage)?
9. The teams can exchange only one player per map during matches.This rule is also supposed to be changed to two players per map.
