As it's been stated by multiple people, a good bomber can take a capital ship out alone. If someone isn't doing proper RP with/for their battleship... It's the admins jobs to punish them in whatever means is neccessary.
As for independent players, there should not be a restrictrion placed on them, no questions asked. If they have the proper RP, then it's fine.
