If you like to play an AI and know how to RP them nice then you should try these ones. It's always funny to see how many different possibilities the AI ID can bring. You can go anywhere at any time. But don't expect friendly encounters only since AI's, and especially the cruisers, are not welcome in the places the lawl syndrome is affecting.
I'm playing now since over a year on this server. And sometimes I thought the same way like you do now.
So I started RPing a Freelancer, and it is always a lot of fun. You can just do whatever you like. (As long as your RP fits to the situation.)
And as Cabulb already said, you can meet some factions and I'm sure that they'll even ask you to join them.
And if it it's getting boring again, just leave and play as Freelancer again.
(I suggest you to write a RP story about your Freelancer, it's more fun to play and it's often easier to RP with others then.)
In the end, it all depends on what/who you like to do/be.
I agree with that. You can go anywhere you want, do anything you want. Personally for me it's too boring to play a Freelancer but that shouldn't mean something for you. Go ahead, try it as a person who is working for him/herself and do some nice RP.
