The problem as I see it, is one that has kinda been stated by GTbrawlers up there.
"If you play with the right people." or "Play with the regulars".
That is not rewarding RP, that is rewarding, for lack of a less intense term, a clique. (Which sounds much more offensive then I intend it.)
That's not saying "You roleplayed well, so you're rewarded." That's saying "You RP'd with the right people."
Which... I mean that's for one, dependant on timezones to ... RP WITH said people. But RP wise, what reason do I really have to go out of nowhere to this group of people that I don't really know ICly or OOCly? Unless THEY come to ME or something happens in a round that forces me ICly into bugging the Captain or whoever, that's ... probably not gonna happen.
It's already grinding karma points to get the thing that's got your eye.
Only you're grinding on an RNG chance to get a Karma point.
Awarding it for Good RP is fine, but when that's your ONLY method of obtaining said point system, it yields problems like this.
And as Daisuke said, RP jobs being behind an RP point gate? sure. Giving a random dude a magistrate cuz he did a lot of mining really well is silly, I agree.
But giving the -gameplay- options behind -gameplay- gates that show you're acquainted with the game, how it works, how to not be a jackass, that makes sense. It makes sense to gate races behind that because of more advanced mechanics.
