Rating Buster - Tooltips with Converted Combat Ratings

About Combat Ratings

The Burning Crusade introduces a new stat called Combat Ratings. These ratings are being used for any combat stat that previously was percentage-based such as: critical strike chance, hit chance, dodge chance and defense skill.

Unlike fixed percentages such as 2% critical strike chance, combat ratings diminish in potency as your character increases in level. 2% crit is the same at every level, while 28 critical strike rating grants 4% crit at level 34, 2% crit at level 60, and 1.27% crit at level 70.

About Rating Buster

These ratings can be a pain when you want to compare 2 different items, is 30 hit rating better or 20 crit rating? thats why I created Rating Buster.

Rating Buster is an Ace2 addon that converts combat ratings in your tooltips into percentages, you can see what it looks like in the screenshot.

In addition to rating conversions, it also has the option to display the Item Level and Item ID, it also works with more tooltips then the ItemLevel addon, so you can safely replace ItemLevel with this.

Supported addons: EquipCompare (will work with all bag mods too)

Slash Commands

Use: /rb or /ratingbuster

{{{ /rb for help /rb targetlevel (10-73) : set Target Level, defaults to your level /rb itemlevel : toggle show/hide Item Level, defaults show /rb itemid : toggle show/hide Item ID, defaults hide /rb usereqlv : toggle calculate using the required level if you are below the required level /rb standby : toggle disable/enable Rating Buster in game, defaults enable }}}

Detailed Information on 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 fomula 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 eazy task, as most people are unfamilier 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 }}} {{{

  1. !html
F=
Weapon Skill 2.5
Defense 1.5
Dodge 12.0
Parry 20.0
Block 5.0
Hit 10.0
Crit 14.0
Haste 10.0
Spell Hit 8.0
Spell Crit 14.0
Spell Haste 10.0
Resilience 25.0

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

Using this formula I was able to calculate a full table from level 8 to 70, I'll put it here for reference: {{{
