To those who think the cave is exploiting, how about say, going to Venus, picking up some Kill or pick up something missions along with a few of the same bounty's and running back and forth from group to group of vex or fallen getting head shots, overcharge kills, and picking up chests and engrams along the way. Farming is farming, its in the game and a part of it. No different than standing at the cave. For a person playing solo when no friends are on line this is a great way to get gear and level up. Have tried the strikes where you are put in a fire team with random players and end up with people getting disconnected, leaving for no reason, or doing a farming run when you want to finish the mission. If you and a mate want to do your own thing don't join a fire team play it in Patrol, don't ruin it for the one person who joins to do a mission. I have much more problem with a person who joins a team and then runs ahead and does his own thing rather than working as a team player and helping all involved. What part of Team don't you understand?
