How will you prevent camping and kill stealing in world of warcraft?

We limit camping and kill-stealing issues by "instancing" certain areas of the game. An instance is a section of dungeon or outdoor area that is private. No other players, unless they are part of your group, can enter your instance of the dungeon/outdoor area. There are also plenty of non-instanced common areas where players can meet and adventure together. http://www.usfine.com
