Playing as a cooperative group did two things to the gameplay experience. First it made it so the new players could learn from the more experienced players and second it brought out some peoples competitive side.
During the game I often found myself lost and didn't know where to go so I normally stayed by myself trying to find allies to help take down these overpowered monsters. But I mostly stayed by myself trying to find straggler enemies as a tutorial as how to properly take down a enemy. The game definitely encourages cooperative tactics so long as you can find teammates and enemies if not it can make for one boring game.
