In my experiences in MMOs and outside it having a long complicated backstory doesn't help, the character will find his or herown voice in play so its better to have a concept and fill in points as needed.
This is I find especially worthwhile with connections to other characters in an MMO, its good to leave yourself some openings incase you change your mind on things or run into a player that just clicks with you in the right ways.
