Player factions are independants with a tag who hold themselves to a certain degree of roleplaying and work as a unified group.
Get 2 or 3 indies and get them to support each other and RP well and whadaya know, it's the exact same as a faction.
The only difference really between faction players and indies are the standards they set themselves. The faction players standards are set, they don't change and are usually held up by others in the faction.
Independents can, if they want, be complete idiots with no consequences, yet they can also achieve things that factionised players can't.
It's a matter of freedom really, independents have more.
And as others have said, get a bomber and do something about it.
