First and foremost, joining a faction is a requirement to playing on the discovery server. You must choose and join one and then mount the proper id for one. Factions are what define what roles we play. This game is about, and always will be about, your faction and it's relations with the other factions in the game. Rant against that all you want, it is the truth.
You've been a member for what ... 3 months? And you're dictating what the requirements are here? Dude ... why don't you hang out and get your feet wet before you start lecturing the rules.
There is NO rule whatsoever that says you must join a faction. As Shryke mentioned ... there's lots of independent ID's to be had and there's lots of role play with those ID's ... so drop the high and mighty routine ... hang out ... and learn from those that have been here a while.
By the way ... what do you think the word "Freelancer" means? Here's a link for ya ... Freelancer.
