90% of the pvp focused players roam around Liberty because it is busy place and they look for easy preys, which is very bad behaviour for a veteran player.
If you want to have better pvp join other groups like corsairs,gallia,unlawful groups etc. Liberty not good for people who dont know pvp that much. Most of liberty players very bad at fighting so you can find yourself in a bad position easly. Liberty had larger fleets like 1 - 2 year ago it was very good for newbies who want to learn something. Now most of Liberty people switched to other groups or left the game
It is pretty dangerous for newbies.
I suggest you to join different groups and leave liberty for good instead of leaving the game.
Other groups can help you out and teach you how to pvp faster than Liberty does.
