Broker: EpicAvg

Broker: EpicAvg is the new name of the old FuBar_GearRating.

What is Broker: EpicAvg?

Broker: EpicAvg is a small addon that calculates the ''EpicAvg'' of you, your target, the party or the raid.

What is EpicAvg?

The simple explaination

Simply stated, your EpicAvg is the (epic) average of the ''item levels'' of each item you're wearing.

The ''item level'' of an item is a number that indicates the quality of an item. This number is not shown by the default Blizzard user interface, but can be queried by addons. For example, Naxxrames 10-man loot usually has item level 200.

EpicAvg is best interpreted compared to common item-levels, like 200 (Naxx10-epics), 213 (Tier 7), 226 (Malygos), etc.

Though EpicAvg works for every player-level, it is used mostly to distinguish between level 80 players.

Why would I want to know a EpicAvg?

The EpicAvg of a person is a '''quick indication''' of the quality of his/her gear-set.

While using the addon, you will get a feeling what a certain EpicAvg would mean.

Beware!

EpicAvg is '''''only''''' a '''quick indication'''. Keep the following in mind:

• The EpicAvg of a person changes if he switches gear. For example:
  • A player in a capital city could be wearing his ''Around Town'' gear-set.
• A person could be wearing gear that is not meant for his Talent Spec. For example:
  • A holy priest wearing his DPS-gear might have a high EpicAvg, but would still be a bad healer.
  • A protection warrior wearing his DPS-gear might have a high EpicAvg, but would still be a bad tank.
• The item level of an item is ''constant'' and therefore:
  • all item enchants are ''ignored'' by EpicAvg.
  • EpicAvg is not influenced by the quality of possibly socketed gems. Therefore, the EpicAvg of a completely unsocketed gear-set and the EpicAvg of a full epic socketed gear-set would be the same.

The complex explaination

Your EpicAvg is not simply the average of the items levels of each item. The notes below explain what factors complicate the calculation.

• Item level 200 on a rare quality item (blue) is different from item level 200 on a epic quality item. Conclusion: It would be unfair to rate items by just their item level alone. Item levels have to be compensated by looking at the quality of the item.
• An item level 200 chest-item has more 'room for stats' than a item level 200 bracer-item. Conclusion: It would be unfair to compare items in different slots. Item levels have to be compensated by looking at the ''location'' of the item (which slot it is in).

So, EpicAvg is the 'average' of the '''compensated''' item levels of each item.

If you want to know ''how'' the item levels are compensated, read the section ''Calculation'' at the bottom.

How do I use Broker: EpicAvg?

Installation

As any addon, place the ''Broker_EpicAvg''-folder into your ''World of Warcraft/Interface/Addons''-folder.

Reading EpicAvg

EpicAvg will be available to you as a LibDataBroker object. The icon looks like a purple chestpiece. Next to the icon is a number. That number is the EpicAvg of the gear-set you are currently wearing.

As you move your mouse over the icon/text a popup appears. The contents of this popup depend on some things:

• If you have a player targgeted, there will be the option "<Get EpicAvg of Target>"
• If you are in a party, there will be the option "<Get EpicAvg of Party>"
• If you are in a raid, there will be the option "<Get EpicAvg of Raid>" You can click these options to get the EpicAvg of other people. Note that since WoW 2.4, it has to open the Inspect-window to be able to get the EpicAvg of other people. So, in fact, if you request the EpicAvg in a 25-man raid, it will open 25 Inspect-windows really fast (and the last one will stay opened).

Broadcasting EpicAvg

On the tooltip, there are some ''captions'', like 'Player', 'Target', 'Party' and/or 'Raid'. By clicking a ''caption'' the popup will change to "Choose a destination to broadcast to"-mode. (You can only click a caption if the EpicAvg belonging to that caption is known.) By clicking:

• 'say', 'party', 'raid', 'guild', 'officer': broadcast to that channel.
• 'target': whisper your target
• 'whisper': your chat-editbox will open with "/gearrating broadcast2player ", type the name of the player you want to whisper and press enter.
• 'channel': your chat-editbox will open with "/gearrating broadcast2channel ", type the name or number of the channel you want to broadcast to and press enter.
• '<<< Back': If you changed your mind and want to return to the normal contents of the popup.

Calculation of EpicAvg

Step 1 and 2 will explain how the item level of ''one'' item is compensated. Step 3 will explain how to sum these up and divide to get your EpicAvg.

Step 1: Compensation for Item Quality

As explained above, uncompensated item levels are different accross the quality spectrum (uncommon, rare, epic, legendary).

To get the quality-compensated item level of an item, do the following: :quality-compensated item level = (uncompensated item level - X) * Y

X and Y being:

• 4.00 and 0.5000 for Uncommon (green)
• 1.84 and 0.6250 for Rare (blue):
• 1.30 and 0.7692 for Epic (purple):
• 0.00 and 1.0000 for Legendary (orange):

These numbers have been deduced from http://www.wowwiki.com/Level_(Item)#Calculating_Item_Level

Step 2: Compensation for Item Location

As explained above, items for different item-slots can have the same uncompensated item level, but 'totally' different 'room for stats'.

Step 2.a: Armor

To get the location-compensated item level of an item: :location&quality-compensated item level = (quality-compensated item level) * Z

Z being:

• 0.550 for Neck, Wrist, Finger, Back
• 0.700 for Trinket
• 0.777 for Shoulder, Feet, Hands, Waist
• 1.000 for Head, Chest, Legs

These numbers have been taken from http://www.wowwiki.com/Level_(Item)#Slot_Modifiers

Step 2.b: Weapons

To get the location-compensated item level of an item: :location&quality-compensated item level = (quality-compensated item level) * Z

Z being:

• 1.000 for Main Hand Weapon
• 0.777 for Off-hand Weapon
• 1.777 for Two Handed Weapon
• 0.777 for Shield
• 0.550 for Bow, Crossbow, Gun
• 0.550 for Thrown
• 0.550 for Wand
• 0.777 for Held in off-hand
• 0.550 for Relic

Note that these numbers have been partly taken from the previously mentioned site, but some of them have been 'guessed'. Check the comments in the code of RatingConstants.lua for the justification of these numbers.

Step 2.c: Hunters

The above numbers cause ranged weapons to carry less weight in the EpicAvg. As this is undesired for Hunters, the following is done:

• Ranged weapon: : hunter location*quality-compensated item level = location&quality-compensated item level * 3
• Melee weapons: : hunter location*quality-compensated item level = location&quality-compensated item level / 3

Note that 0.55 * 3 = 1.65 making the ranged weapon of the hunter almost as important as a 2-handed weapon.

These formulas cancel eachother out when it comes to EpicAvg, which is convenient if you still want to be able to compare Hunters to other classes.

Step 3: EpicAvg

So, now we have the ''compensated'' item-level for each item. Simply sum these values to get the: total compensated item-level, abbreviated to ''tcil''.

So, the question that we ask ourselves is: "What epic-item-level would 17 items have be, to get to the same ''tcil'' that my gear has?"

To answer this question we have to solve the following formula:

:(X - 1.3) * 0.7692 * 1 + (X - 1.3) * 0.7692 * 0.55 + (X - 1.3) * 0.7692 * 0.777 + ... + (X - 1.3) * 0.7692 * 0.777 + (X - 1.3) * 0.7692 * 0.55 = ''tcil''

We can substitute U = (X - 1.3) * 0.7692 to get:

:U * 1 + U * 0.55 + U * 0.777 + ... + U * 0.777 + U * 0.55 = ''tcil''

This can be shortened to:

:4 * (U * 1) + 5 * (U * 0.777) + 6 * (U * 0.55) + 2 * (U * 0.700) = ''tcil''

Which simplifies to:

:(4 * U) + (3.885 * U) + (3.3 * U) + (1.4 * U) = ''tcil''

Which simplifies to:

:12.585 * U = ''tcil''

Now, U is the answer to the question: "What LEGENDARY-item-level would 17 items have to be, to sum up to ''tcil''?"

Remember U = (X - 1.3) * 0.7692

Now, X is the answer to the question: "What EPIC-item-level would 17 items have to be, to sum up to ''tcil''?"

So, to conclude, to calculate the 'average' epic-item-level the formula is: :((''tcil'' / 12.585) * 1.3) + 1.3

This formula is used to calculate the EpicAvg.
