PvP right now seems a bit overpowered, the fact that you can walk up and kill players without their consent and even on their own land is just outrageous, if you didn't lose everything it might not be so bad. I think players should have some sort of defense because players just starting out don't even have good armor for atleast a week. I propose that players can't kill other players on their own land or even not be able to kill them without their consent. I know it's realistic that you can walk up and murder someone and that it costs like 100000LP to be able to do so but it is a major game killer if you work for a week and before you're even able to make armor and weapons a person walks up and slaughters you causing you to lose everything.
tl;dr - change pvp by making players consent to combat or not be able to be killed on their claim.
