Family only in our FC. That's how it's always been in any game we've played for the most part. We have a nice group of four right now for a perfect Light Party. That's all we really want--to be able to get each other through the group content (though we're dreading the Full Party stuff we know is coming), since we're all more into the solo content than the group stuff. Totally not interested in pugging or even interacting with anyone else.
