I personally want the whole cost analysis and gold efficiency gone from this wiki for several reasons which I shall once again lay out here.

Missing and Dynamic stats
There's several stats that don't get taken into account, and some we can't place a value on because their efficiency is based off of other changing stats. Some examples here would be Percentage movement speed, Armor Penetration, Magic Penetration, etc. There's more on the list that aren't reliable or fixed in place, these are just some of the biggest ones that can't be calculated and are a big part of at least half the items.
 * The % MS is based off flat ms which can and is capped by two hidden speed caps.
 * The armor and mr penetration can't be reliably calculated because it's gold efficiency depends on how much armor and mr is owned by the opponent.

Misleading Information
Gold efficiency implies a worth to an item that is there every game. However the cost of an item and the effects you get from it do not determine how efficient you spent your gold on your champion. We can all agree that buying on  isn't a very efficient use of your gold. Yet the cost analysis doesn't show this at all, seeing as it's 102.8% gold efficient on its own! So it must be worth that amount of gold in the stats you get on everyone, RIGHT!?

Trivial Information
Gold efficiency is not actually vital or even useful information. It's just like background and trivia of Champion pages; Interesting if you like that stuff, but doesn't do anything for you in game. (Darius shares a line of text with Quinn, YAY!)

You could argue that it would help you to determine which AP item to get, if you doubt which one is more bang for your buck. But that's again arbitrary information, since you should judge items for what they give you and your champion and if it does or doesn't fit your role/playstyle in the game you are playing.

Maintenance
The calculation and editing of each of these items has to be done manually at the moment, right? So that would take up a lot of time to initially do correctly. And every time something changes someone has to go and manually edit all of it... If they were to change armor and mr to be a different value then they are now, you'd have to edit over 50% of the items that have the section...

Conclusion
In my opinion, it's too much trouble to calculate and maintain arbitrary, misleading and incomplete information in this manner.
