We need a pvp mine in prison for people that have (Free-Man) and above. This would make prison way more fun, and overall i think prison would be more active.
Players with Free-Man can already fight in the free world, they could even make their own arena to fight in. Plus, if this was added, PvP on Prison would be more diverse and with the lack of PvP currently, it won't bring much action to the server (because of the separation of the main PvP zone). No support.
It would probably end up just being unfair so then no one would go there and it would end up being a dead area.
