For the Binocular end mission all 4 players need to be on the same stage of the mission chain or they cannot jump down to the traffic transports. So you need to find 3 other people on the same exact stage of the mission.
So you are willing to create a new character, level to 55, go through the mission chain, get to the same stage of the mission to help. Then, do that all over again for the next person who needs it? That is awesome.
