[Take the Central building in Firebase Ghost. Two overlooking the back alley, one overlooking the connecting building, and one watching the back ramp and the ladder. Each individual gets a "Killzone" and if they require assistance with some bigger enemies, one person (Or two depending on each individual's situation.) can move to assist. No one is directly interfering with another, and each person is independant.
Lone-wolfing isn't recommended, but if they cannot watch and/or defend a position, or don't know when to call for help, they're not doing their job, not helping the team.
A group of independant players can fan out and engage the enemy if they know how to play their class. I'd refer you to some of the gold runs we've done, but I don't have any ability to capture/show you. 
It might be me that is not a good enough player yet to truly understand that you can do that on gold. I havent played gold yet with my mates, might also be that my highest level is 15 and trying them all to find the one I like playing.
My Krogan Soldier can kill alot, he is level 10 if I remember correctly and I wouldent like running by my self when there is phantoms. Most others is no problem for the soldier krogan.
But I would like to se some fotage of gold and a soldier, cuz as I sayed it might just be because I am not a good enough player to see it yet.
But for me I love that I am dependent of others to do the harder challanges so it trully becomes Teamplay.
But in some PuG or what you call it I hear that frag stealer and I just have to say if you walk together and help eachother it will happen. And in PuG you cant be as efficient as in a group you have been playing with for a loong time.
But I hope getting to Gold soon. Then I can see maby what you meen.
