Allow me to clarify, then:

"League of Legends Wiki

"The Brutalizer's 10 flat armor penetration must be valued at 15 gold for this item to be gold efficient."

With the rise of new theorycrafters, we've also seen a warping of the current system. Some people have the concept of "item efficiency" in their head, but it's often the wrong idea. If you look at different items on the LoL Wiki, you'll find that generally the item efficiency explanations don't make a whole lot of sense, and in many cases they're even wrong."

This is followed by a paragraph explaining how the idea of item efficiency has slowly corroded over time into the sole determinator of an item's worth. At least to me that's implying the article author believes the wiki is part of the problem.
