This server is known as a PK server, the changes you all seem to want will lean towards a PvE server where only real PvP action would come forward in the PvP rooms.
Though the PvP rooms aren't really crowded and won't seem to be, will this turning PK off result in more people in the PvP room? I doubt it.
Yes it is annoying to get killed while you're hunting, but who says you can't fly wing, warp or teleport away?
Do you have to go to that area where all other players are camping? No you don't, but it's the inescapable urge of people to go towards a group, to socialize or to be with others even if that means they'd be killed.
Use those fly wings and move along.
