Honestly I didn't even join an FC until I was well into the endgame.. (yes I waited out all those story queues by myself, as DPS) I was solicited many times, but only one person who actually spoke to me about joining an FC was nice enough to, yanno, talk to me as a person instead of "join my fc" only. Ended up joining their FC about a month after I joined the game (I had finished the 2.0 story and was going through the patches, and working on my relic...this was probably back in November). We're all close friends now.

A board or something..would be nice to search but really the only way to find an FC for you is to talk to people.
Good luck
