They intended to fight, to fight in the Lord's area. They did it because they wanted to get a second Lord. That is one way to win this second-round match.
The Jungler from the Bengawan team continues to attack the Lord with the help of Hanna. Jinxpro continues to attack using his Basic Attack. But meanwhile, the players from the MB team are among the bushes, to take the Lord.
The Tank of the MB team has opened the war. He had advanced to the front, where the Bengawan team's players were attacking the Lord. He was only provoked there so the Bengawan team players hesitated to attack the Lord.
