End the Greifing and make PVP a mutual agreement

We haven’t even been in the Beta for more than what 4 days total? and the PVP Greifing is out of control. People join the games with a PVP build and come in and kill the entire party who is trying to PVE. You need to allow people to decline hostility.

Sorry dude but i just wanted some gold

Also there werent pvp games and when i created one, nobody joined so i had no other option than hunt you down to have some adrenaline.
