There will areas that the persistent server stacks more to NPC encounters (PvE) than PvP. You'll gain greater reputation by negotiating the tougher areas though, which will be more towards PvP.

I'm also considering letting players set a rating on their willingness for PvP, if they want / like PvP and want to move up the leader boards the persistent universe server will match them against real people much more, but if you don't it will be more NPCs.
