There has been some question over whether pages that have "Contains _______" should also have this category attached. I am of the opinion that such a cat would be overly large, and thus not helpful, and if a user navigated to this page, he could focus more on specific rare mats to salvage for. --JonTheMon 12:38, 30 October 2008 (UTC)

Agree. I have proposed an alternative solution to the concerned user on my talk page. —Dr Ishmael Diablo the chicken 14:53, 30 October 2008 (UTC)
