At the risk of stating the obvious... Why not abolish limits for pub freqs altogether? So the whole server gangs up on the priv freq. So what, they're vets on a priv freq, they should have to be challenged. If the pub freq wins, the jp is hopelessly split across many people, so it's not like the motivation to go priv goes away. I'm sure flagholders on the pub freq will break away and start their own priv freqs to steal the jp, starting the cycle over again. If you're worried about 1 giant pub freq ganking everyone, well, that state never lasts very long because 1 giant pub freq doesn't make any money.
