If this is about Archon's Forge, then I honestly don't see the point. It's a very simple matter to find an active Forge instance. All you have to do is walk (not sprint or drive) through the transition areas and give the game more time to find other players. You're more likely to find other people coming up from the Warrens than coming in from outside, as the transition zone is longer. And besides, once you hit about 350 light, even the Perfected become really easy with three or four people involved. I mean there's not really much of a reason not to make a six-player patrol, but there's also little good reason to do it when most people probably fly solo in patrol.
