1: Official factions often make you wait ages before you can fly a cap ship you want, if you are an indie you can have fun with it straight away.
2: You may not agree with the RP of the official faction, and so want to start a faction more in keeping with what you think that ID SHOULD be doing (possible one)
You mentioned official factions in your opinion.
The opposite of indie is being official
Why can't I talk about official factions?
No indies = Indies being faction members
When indies have to join factions to be able to say have a navy ship but...
They also want to fly a military ship they ahve to join that official faction too.
I can't see how I'm off topic.
Or do you mean all indies have to fly generic ID's such as Freelancer?
