Valuing Items by Runes

[mcgriffin]

Disclaimer: the following calculations and interpretations are only meant to be pure maths games and serve as self-entertaining purpose only. This is no indication or has any valuation value to the usefulness of the items in the game, nor do I intend to engage into any argues on the validness of this whole idea (of valuing items with runes). However, any discussion on the modification/improvement of the idea/some specific formula, or additions of new items/sets, are welcomed. I'm open and glad to have any discussion if it's not just 'bah, this is meaningless' or 'it's a waste of time' sort of reply.
