Item Efficiency Chart?

[quote=Visfarix]A couple months ago I found an Item Efficiency chart on the Solomid forums, and thought it was a rather nice tool for theory crafting and proceeded to download it. However when I took a closer look, I realized it was a bit out of date at the time. It's been around 3 months since I picked it up and now it's way out of date. So I decided to update and reformat it for personal use, and now that I'm about 80% done with it, I realized, "Hey maybe some of you guys might want to use it too". So now my question is, "Do you guys want to use it too?" If you do I'll need a couple volunteers to look through it and proofread it in case I made any mistakes. Plus I'm a bit iffy about some of the items/statistics so I'm a bit hesitant to just release it as is...[/quote]

[quote=Mowen]This sounds really useful. However, I am pretty bad at math! :( So I'm afraid I can't help much. Tell me if you want some photoshop skills though. ;)[/quote]

[quote=Adonikam]This would be sweet, I'd love to help if you told me the formulae.[/quote]

[quote=Visfarix]Hmm well, here's the link to the spreadsheet. Take a look at it. Tell me what you think. Advice, suggestions, etc. [url=https://spreadsheets.google.com/ccc?key=0AlMkqp-iRtEEdDFSV0ZnZElpY2NmNXF5anZEcThDSEE&hl=en&authkey=COC_6-AM]https://spreadsheets.google.com/ccc?key=0AlMkqp-iRtEEdDFSV0ZnZElpY2NmNXF5anZEcThDSEE&hl=en&authkey=COC_6-AM[/url][/quote]

[quote=Jebus McAzn]Where's the "other items" chart? I personally find it difficult to rank items like that and the chart probably won't affect my gameplay too much to be honest.[/quote]

[quote=Visfarix]At the bottom of the spreadsheet are tabs for you to scroll through the other available charts. My chart is based off of the chart posted by Dret on the Solomid forums. Here's the original thread and chart if you're interested, though it is pretty out of date. [url=http://www.solomid.net/forums/index.php?/topic/1797-item-efficiency-spreadsheet/]http://www.solomid.net/forums/index.php?/topic/1797-item-efficiency-spreadsheet/[/url] Yea it's very difficult to rank items by efficiency and TBH efficiency shouldn't effect basic theory crafting by too much since all items are pretty unique in what they do. I find the main use for the item efficiency chart is in helping one determine item acquisition order or determining which item to drop/pick up when faced with a tough decision on which item to get. Lots of times it doesn't even matter if an item is inefficient or not, especially if that's the item you NEED. Another nice thing about the chart is that it shows some of the items that aren't noticeably OP or UP until you see its efficiency. For example, Rabadon's Deathcap is seriously OP. If you farmed up the gold and you don't need the survivability too badly, [b]Deathcap should be the first AP item you get[/b]. It pretty much gives you 730g worth of AP for free and it continues to give you .3 additional AP on all new sources of AP you get, [b]giving you even more free gold[/b]. Compared to the original Zhonya's Ring, Rabadon's will give you over 1000 more gold in AP. So yea item abilities and what they do should definitely be considered 1st and how efficient items are 2nd.[/quote]

[quote=Shrillex]Great job on updating it! The other is seriously out of date.[/quote]

[quote=Visfarix][quote=Shrillex] Great job on updating it! The other is seriously out of date. [/quote] Thanks! It took some time but I'm rather glad I did it. These efficiency values are pretty informative and are helping me get a better perspective on these items, especially the newer ones. However, I need some feedback on these things: 1. I'm not sure I did the cost evaluation for Spell Vamp correctly. Currently I have it set at 15% spell vamp=330 gold, because that's how much it costs to upgrade 2 amplifying tomes into a hextech revolver. The problem is that 2 amplifying tomes cost 870 gold whereas the the stat value of AP is 1AP=20gold so on hextech revolver the 40AP would be 800 gold and the Spell vamp should(?) cost 400 gold. But it can also be argued there is a cost to combine 2 items into one. So my problem is, should I use 330gold or 400gold for the value of Spell Vamp? 2. Should I include Cooldown Reduction as a measurable efficiency stat? Because Riot introduced Kindlegem, I think it would make a fairly accurate measurement for the value of CDR.[/quote]

[quote=caucheka]yeah i looked at the old efficiency chart when making my items. the recipe was 400 for 100 mana, 6 mr, and 10% spellvamp mana and mr were easier, but that left 150 gold for 10% spellvamp well shit thats so much better than the most efficient spellvamp item[/quote]

[quote=ThomasterXXL]I "updated" that chart myself some time and now I put it on the LoL-forum and realized that it peaked nearly no interest there, so I'll try and see if anyone here would be interested in taking a look at it and telling me what exactly they think I made better/worse than in the original. In the end I only made that spreadsheet for myself and ended up colouring that stuff, turning the item-effects into tooltips and adding the option to guess the values of penetration, CDR and MS based on quints. Other than that you can factorize a stats usefullness: 1 as Standart and 0 for useless anything else depends on your own opinion. (like 0,4, because AP is ALMOST useless on Pantheon) I'm just trying to get some opinions on it.[/quote]
