I really have to agree with mjolnir about that people go to extreme lengths in oorp to get as competitive gear as they can get. And this makes balancing issues very hard. it's amazing how many guns & ships Disco has. There always is a "winning" combination out there.
The sad fact is that there are always people who have pvp in top of their list in mind. As these people go about they will win battles. Then those who stick to RP are disafvantaged. And nobody likes to take a dive all the time, so they gear up also.
I think the most critical component is the critical mass of players who dictate the direction in weapons and equipment. With critical mass I mean people who have RP weaponry and have a fighting chance in most of the fights. If the balancing folks can keep this critical mass relatively happy then Disco has a future as a RP server.
