About RatingBuster

RatingBuster started out as an addon that converts combat ratings in your tooltips into percentages, so that you have more meaningful information when comparing different items.

The design aim of RatingBuster is to provide detailed, meaningful and customizable information about items so you can easily decide for yourself which item is better.

Features

• Supports talents, buffs and racials that modify your stats for all classes

• Fully customizable, decide what you need to see and what you don't want.

• Rating Conversion:

  • Converts combat ratings into percentages.

• Stat Breakdown:

  Breakdown Strength, Agility, Stamina, Intellect and Spirit into base stats.

  Supports talents, buffs and racials that give you extra bonuses.

  Ex talent: Lunar Guidance - "Increases your spell damage and healing by 8%/16%/25% of your total Intellect."

  Ex talent: Heart of the Wild - "Increases your Intellect by 4%/8%/12%/16%/20%. In addition, ......etc"

  Ex: +13 Intellect (+234 Mana, +0.18% Spell Crit, +3.9 Dmg)

• Stat Summary:

  Summarizes all the stats from the item itself, enchants and gems, converts them to base stats and displays the total value and/or difference from your current equipped item.

  Ex: Crit Chance - Adds up agility and crit rating from the item, enchant and gem. Converts agility and crit rating to crit chance, and displays the total in a single value.

• Item Level and Item ID:

  Item Level is obtained from the WoW API, not a calculated value.

  Item ID is useful for advanced users.

Auto fill gems in empty sockets

1. You can set the default gems for each type of empty socket using "/rb sum gem <red|yellow|blue|meta> <ItemID|Link>" or using the options window.
2. To specify the gem of your choice, you will need to give RatingBuster the ItemLink or the ItemID of the gem.
3. ItemLink example: type "/rb sum gem blue " (last char is a space) and link the gem (from your bags, AH, ItemSync or whatever), then press <enter>.
4. What if you can't link the gem? Well thats what ItemID is for. Find your gem on http://www.wowhead.com/ and look at the URL, for example "http://www.wowhead.com/?item=32193", 32193 is the ItemID for that gem. Go back in wow, type "/rb sum gem red 32193" and press <enter>.

Note1: If you have "/rb sum ignore gem" on, the auto fill gems won't work.
Note2: Meta gem conditions and SetBonuses work, so if you don't meet the conditions, StatSummary won't count them.
Note3: RatingBuster will only auto fill empty sockets, if the item already has some gems on it, it will remain.
Note4: Empty sockets filled by RatingBuster will keep the "Empty Socket Icon" so you can still easily tell what color socket it is.
Note5: Gem text filled by RatingBuster will be shown in gray color to differentiate from real gems.

How I derived the Rating Formula

As soon as I saw the blue post on combat ratings system, I began to think about coding this addon. But Blizzard only gave us level 60 and 70 data about this system, and for an addon like this to work you need exact formula that will work for all levels. So I need to reverse engineer the Combat Rating formula, and the process of obtaining this formula can be broken up into two simple steps.

1. Get more data

In order to obtain the exact formula, I will need more data points then just level 60 and 70. So I logged on and started asking random people about their crit% and crit ratings show in the Character frame, the problem was the crit% shown only has 2 two decimal places, which turned out to be insufficient for this matter.

So I started to dig in the DefaultUI lua files in search for a new API that will give a more precise crit% and I came up with this script /script DEFAULT_CHAT_FRAME:AddMessage(GetCombatRatingBonus(9)).

Now I need to log on again and ask random people to type that script and tell me that 13 decimal place crit% that it shows. This was not an easy task, as most people are unfamiliar with lua script, there are even people that immediately put me on ignore after I sent him this script lol.

After hours of work, this is what I got:

2. Think very hard

After some creative thinking, this is what I got:

Percentage = Rating / F * H
Lv 8 to 60: 1/H = 1/52 * Level - 8/52
Lv 60 to 70: H = - 3/82 * Level + 131/41

This formula is correct to the 13th decimal place, so I'm 100% sure this is what blizzard uses.
