Faction can be consisted of a different characteristic players, some might be sex crazed psychos, some might be professionals,some might be just crazy psychos and so on...That's the most interesting part of this game and in this faction, if you ask me, that there is no monotony. But as an union they might be acting for their goals, intentions and purposes, and what I have been witnessing the Commune as a faction has its own goal and roleplay, which they manage to follow successfully.
I, personally, prefer this kind of factions which isn't consisted of the members whose RP lines are the same as every other members. It's kinda boring encountering the members of official factions and hearing the same RP lines from them, which they have set on their -setmsgs-, and by typing "/l1,2,3" all the members of the faction write the same RP.
This was my personal opinion about factions with different characteristic members.
P.S I'm not objective here, as I'm a big fan of diversity in games and in real life too.
P.S.S If I was a trader and encountered criminals right next to the station where I can simply dock, I wouldn't really expect from them to display their whole RP, instead I would expect from them exactly the same interaction. Trust me, if there was no possibility that you would dock, there would be different RP from my side.
