Faction vs Indies, a little off-topic rant then...
Tell you the truth, you'll see faction members roleplaying good, and you'll see indies roleplaying good... and obviously the other way around too. It's up to the individual player how good you are at roleplaying, you don't magically become a super roleplayer just because you've earned a faction tag. Sure, sure, factions won't accept just any "noob" into their ranks. But people, come on! Just because you're an independent player doesn't 'automagically' make you a cap whoring OORP blabbering idiot, does it ?
On topic then...
Make cap ships more expensive, with stronger firepower, but weaker against attacks.
