I'll concede Leia to you, though I still think she took her fair share the smart guy role.
Something I think we have to remember is that even in role playing, you'll see this (what, you must have wondered why they suggest on groups of 5 players before, right?). I think it's just human nature. In a group when you're working towards similar goals you will automatically start moving towards the spot that you fit best.
It's really interesting to look at your group of 4 closest friends and
figure out where you would fit into this (though as with anything,
sometimes it doesn't work... human interaction never flows quite as
easily as it does in the stories).
For me, I would be the Chick. I am usually the one mediating differences in my group of friends. I'm not the bravest, I'm not the strongest, I'm not the smartest and I'm not even usually the second... But I am the one that all of my friends say would support them through the hard times and I am a enabler like nobody else (of course you can! Why would you think you can't?).
