"Kills don't mean anything" True. But team play does. Unless you're soloing the strike for example you're part of a three person TEAM. So play as a team. Not as an individual. That's not too much to ask for. Again, given the fact it's a team activity. I don't mind if someone gets a little bit ahead. As long as they remain in sight, preferably where one of us can get to them if they are downed. Farther than that is not cool. In addition, as we all know, it takes longer to self-revive than it does for a team mate to revive you. Or for you to revive them. That means if three players are all dead and strung out across the map it's going to take significantly longer to complete the mission, especially if it keeps occurring. Hence, nobody has a good time.
