PK has no place in this game. I personally think it has no place in any game, it's purely a mechanic that allows people to get their jollies by picking on lowbies. I genuinely don't understand how anyone can enjoy what amounts to trying to destroy someone else's playtime on purpose =/

By all means, ask for a PK server. Just don't complain when the only 10 people that use it are griefers, because that's what will inevitably happen.
