Launch of Item Efficiency Lite!

Welcome back to the Sunday edition of #VVinning/A DIFFerent View.  Before I start, I'd like to thank all of the readers for the successful AMA/giveaway event yesterday.  For myself, the team AMA was the second greatest event I've been able to be a part of as part of the ADV team (the greatest being the RoG launch).  With over 900 comments and counting in less than 24 hours, we had a great time answering your questions last night and we'll probably continue answering questions today.

Before I go into today's post, I'd like to share a mini-autobiography that I didn't get to share during the AMA.  As many of you may or may not know, I started theorycrafting through a whim: I was curious as to how gold efficient items are in League of Legends.  This curiousity led me to expand on other early mathcrafters' work through the original incarnation of my item efficiency spreadsheet that was on the reddit /r/leagueoflegends sidebar for almost a year. After all, if you're going to spend 100's of hours playing a game, why not spend a few hours and give back to the community?

As for my A DIFFerent View background, I first met DiffTheEnder in the end of December 2011 when he first started blogging on the old RoG, and I was inspired to help him blog because ironically...Diff was the worst mathcrafter I had ever seen.  From what he tells me, he wanted to run a fun-and-games blog, not a theorycrafting blog.  His posts were literally so bad that we still have an inside joke that the hexdrinker shield is equal to 12 mr in our chatroom.  Since then, we've come a long way, and we'd like to thank you the readers for supporting us in the last 5 months.

On May 6, 2011, I released my first theorycrafting work.  Today on May 20, 2012, I want to share a condensed and slightly improved version of the original in the form of Item Efficiency Lite!

Item Efficiency Lite

As you can see below, my traditional Item Efficiency calculations have excluded many statistics that I do not consider important, chiefly HP5, MP5, Spellvamp, Arpen, Mpen, CDR, and MS. In the fifth column of Item Efficiency Lite, I have done the efficiency calculations for items that include these secondary calculations.  If you look below, there is a reason that I usually exclude these statistics: if we were to take base values for these secondary attributes into account, many items that are weak in the current game such as Archangel's Staff and Soul Shroud appear much stronger than they actually are.

Passive effects for the most part are NOT included in the secondary statistic calculations.  If you are a player that knows what most of the items do in the game, it would be a wise decision to ignore the really shitty and bullshitted notes column.

Due to some problems with both javascript tables and embedded links being disabled on Reign of Gaming, I have provided an image of Item Efficiency Lite below.  A nicer version of the table/picture I've put below can be found on google docs or by clicking on the second tab in my original spreadsheet.

    And at end of the day, atmogs/frozmas is always going to be more efficient no matter waht!

    i think this is pretty misleading, the efficiency of an item cannot be calculated so simply. For example Deathcap is, imol, the most efficient ap item because it scales your total AP comulatively with its 30% boost. yet it only has a rating of 40. And most of these items shown here have negative ratings, but many are commonly purchased, because their value cannot be counted simply through cost efficiency.

    Not really misleading if you understand that the 40 rating is without any ap. In the sidebar it says that it also adds 30% ap. You gotta remember these are not taking into account ms, regens, cdr passives/actives (unless calculatable).

    An item like frozen mallet can be super efficient because of how powerful a slow is. You just have to know that it "sucks" based off of hp + dmg alone.

    How do you define (and calculate) the efficiency of an item? I'm going to assume that that more is better since a stacked bloodthirster has a higher value than an empty one, but seeing the spreadsheet doesn't tell me much without knowing what is being calculated here.

  • #4 tgo007

    a long sword cost 415 and provides +10 damage. A BT fully stacked provides 100 damage and cost 3000.

    Based off of long swords it should cost 415 x 10 = 4150 and that's not taking into account lifesteal.

    So you're paying low for a lot of stats.
