If people want to PVP, they can enable it, if not, disable it.
And before the world PVPers start the Ad Hominem attacks, let me explain.
I don't always want to PVP, sometimes, I just want to do quests or collect herbs, skins or ore. I already have to deal with mobs, I don't need a level 80 whacking me when I'm not looking.
And that brings me to the next point, why are level 80's going into level 20 zones and killing players 60 levels below them? What's the challenge here? I know I haven't seen level 80's flocking to the newbie areas to slaughter boars all day long, so why is this occurring? Is it padding stats? I would hope those kills don't count for anything, just as slaughtering newbie area boars do not. If it is to grief these low level players, then these people have several mental disorders, one being narcissism, this is your world and we are just living in it, and the other sadism, you take pleasure in the suffering of others to make yourself feel better about your seemingly miserable existence.
So anyway, that's my suggestion, hope others find it helpful.
