Talk:Gold efficiency/@comment-190.37.255.158-20130327154454/@comment-5266525-20130410102936

This page is a repository telling you, more or less, exactly what you are paying for when you purchase an item from the store. Something that can't give you as many raw statistics for your money as the least efficient basic-tier item (incidentally this is why we use the least efficient items in the wiki calculations) has to owe its gold disparity to any unique passives it has.

Keep in mind that by itself gold efficiency isn't necessarily a measure of how good an item is. It is just one facet of the answer to that question.

Beyond that, your question's too general for me to answer.
