The best way to make friends is to start with a mutual interest. It certainly helps if you're a leader or pioneer.

Try making server-only groups in party-finder for content you enjoy, and then you can judge the people you get. If you click-push for a second date--err, social event. You can easily make friends by throwing together map parties, and even easier if you offer to pay for all of the maps. You'd be rolling with your own crew in no time!

The bottom line though, people generally only care for others based on what they can get in return. Some folks just want a partner to not feel alone, others need a partner in crime to run some duties. Others just want to empower their FC mates, and in turn--fuel their own sense of tribalism. The best relationships are those where both parties mutually benefit from each other. Goes with the popular saying 'the best way to have a friend--is to be a friend."
