and it happens all the time. for example, i join a pve mission against the borg. i try to discuss strategy before it starts and the other 4 players all take off in different directions weapons blazing. meanwhile i'm trying to protect kang and start getting hammered and no one comes to help. ships start blowing up left and right, name calling begins and we lose the mission.
i do get lucky at times and get with a good group that makes the missions really easy to achieve. i love getting borg stuff. need more maco 12 gear. :-)
i am trying to join a fleet to be able to work in a real team environment to increase the success on missions.
