Making it more interactive in theory would help justify having a full party, but it the end it will likely just annoy people after the novelty wears off. The trouble with the Light Party requirement is that for whatever reason, if a small or solo FC can't get 3 other people to help them out within a reasonable time, they get frustrated and it becomes a waste of their time. It begins to feel like a unfair layer of frustration penalizing smaller FCs over larger size FCs. Thus, this system actually encourages people to just migrate towards medium-to-large FCs to not deal with the hassle of the airship restrictions rather than try to start or manage their own FC. Small FCs should be able to thrive and not be penalized for their lack of numbers. I'm more conflicted about solo FCs, but I get why some people opt for them so if they're putting in the time and effort to do everything themselves, go for it. So yea, maybe a scaling requirement based on FC size? Like 1 person if your'e in an FC of X amount of people or less, 2 if you're in an FC of Y people or less, and so on until if you're in an FC of Z or more, you need 4 people.
