Deletion of DKP (2nd nomination)

Comment: The purpose of  is to prevent pet theories, not to remove articles that describe current and undeniable phenomena. The article does not, in any way, advance personal agendas on the part of any of the editors, near as I can tell, except the desire to, I don't know, create an encyclopedic entry on a specific topic. Previous usage of the term in academic paper is also discoverable on http://scholar.google.com/scholar?hl=en&lr=&q=%22dragon+kill+points%22&btnG=Search Google Scholar. In other words, the term not original. Also referenced by Nick Yee in his http://www.nickyee.com/daedalus/archives/001313.php MMORPG Lexicon. You ask for reliable sources, but fail to note that all of the external links are, in fact, primary sources. They are examples of DKP systems in use
