I think there's something to be said for it being up to the players but I'd enjoy activities designed specifically for light to full FC parties, because that's what I do when I'm not solo. It's what's worthwhile to me even though it's not regarded as any sort of accomplishment, game wise, which is why I mostly agree that any group will be what people make of it. Still, this game gives the feeling that it's the "wrong" way to play and the "right" way is with a new group of people that you'll probably never meet again. It could be more balanced, with a reward system to encourage both.
