So PVP
1) evidently battleground – twice a day – kill if you dare but watch the consequences as always
2) wild bosses – you can attack other players in the vicinity I believe but servers are small
3) mining – you can attack between certain hours and savage innocent miners – again I advise the servers are small and you will be nuked
Ultimately this is not a massive pvp game so be smart – pick enemies only if they offend first – and well the rest I wish you well.
