I really don't care about pk at all (never have) and those that do it just annoy me when I go out of my way to avoid them. I don't attack people. I don't role play unless I have to deal with someone because I don't want to make their play time less enjoyable. I don't participate in cabals or their politics. I usually play tanking characters so I can level people up and have fun with them since tanks are hard to come by for groups. All of them are fucking villagers or just dicks.
I would like to see something along the lines of being able to opt out of pk and just explore. I don't care if they make it where you can't keep limited gear for longer than a week or whatever because you aren't doing pk to keep the stock fresh. Most people don't really loot much any how. If someone is leveling up by their self and hasn't ever interacted with you before then leave them alone. Don't go and kill them then return again just a bit later to attack them again then chase them down when they clearly are not trying to put up a fight but trying to get away. If a person lets you kill them and they don't say anything right afterwards but you see they are still sitting in the same area just trying to level up...they probably just want to be left alone and don't care about you.
