This seems to be generally true, but the odd exception occasionally comes up which prevents us from saying that the game "always" uses the exact value. For example, in WotLK it was demonstrated that +hit only transferred to hunter pets as a truncated integer, meaning that 7.99% was no closer to the cap than 7%. It pays to verify such things because you never know where inconsistencies might creep in any time combat mechanics are changed.

Mana Regeneration
4.0.1 Changes:

I assume everything written related to mana regeneration there is listed as MP5, as gains per 5 seconds? If so, could you add that info in a line there since quite a lot of TC uses MPS, so it's not always clear what everyone is talking about.

Base Mana
It's not exactly a Combat Rating, but still the basis for everything related to mana costs. Base mana is the amount of mana you'd have if you had 0 intellect (not +0 int from gear, but a total 0 int), it only depends on class, not on race, and is the basis for spell costs and some other effects. It would be nice to have that added in the OP.

Priest = 20590
Druid = 18635
Mage = 17418
Paladin = 23422
Shaman = 23430
Warlock = 20553

Base Health worked like base mana up to level 80. It seems to be different now at level 85 though, not entirely sure what's going on there.

For each level beyond 80, stamina grants an additional 8% health per point. This bonus caps at 40% at level 85 and onward, resulting in a conversion of 14:1 beyond the first 20 points of stamina.

EDIT: Updated to reflect stamina's present state in MOP.

The base regen value for 85 is 0.005575 and not 0.003345.

Level 81 and up:
$DR=\frac{Armor}{Armor + 2167.5 \times Level - 158167.5}$
Level 60 to 80:
$DR=\frac{Armor}{Armor + 467.5 \times Level - 22167.5}$
Level 1 to 59:
$DR=\frac{Armor}{Armor + 85 \times Level + 400}$

For tanks, you will want to know what's the armor cap when facing level 88 bosses, here's a quick table:

Armor Reduction for level 88 attacker	Armor needed
50%	32572.5
55%	39810.8
60%	48858.7
65%	60491.7
70%	76002.5
75%	97717.5

My main goal is to justify using [Unidentifiable Organ] vs. any other trinket because it has much more armor compared to level 85 armor trinkets. I assume [Leaden Despair] is a given. I also wish to find a definite EH value for armor.
(All gear assumptions are for pre-raid gear.)
I was looking at the numbers for the 81-85 bracket. In order to get the 75% from 97717.5 armor, the input "level" was 88. This was also true for the other percentages in the table. I looked at my damage reduction in game. After I switched into my DPS spec and gear to prevent any possible armor modifications via a meta gem or talents, I have 19136 armor. It says I have a 42.33% damage reduction. I then proceeded to plug in my armor into the above equation. When I used 88 as the "level," my percentage for damage reduction was calculated to be 37.0071%. However, when I plugged in 85 as the "level," I calculated 42.3302% -- the same as it reads in game.
(I did some rearranging later with gear and meta gems, it appears the game accounts for those modifiers.)
Before I continue my justification, I need to know some of the invisible in-game values they plug in to those equations to get what is shown in the game tables. Based on your table calculations, the "level" is the opponent level. Assuming your equations are correct, does the game equation assume you are fighting a level 85 enemy? To include another possibility, although it is far less likely, the "level" to plug in might be character level instead of the enemy level. I am not sure, but I would like to know.
One last thing, to make a comparison for later, was the EH value for armor 11 armor to 1 stam (at level 80 in WotLK)? Also, is the 60-80 bracket the same as it was in WotLK? If not, what was the armor equation at that point (pre 4.0)?
Thank you.

I'm seeing the new 2167.5*TL-158167.5 formula everywhere but I don't see it's expanded form, anyone know what it is?

Pre-Cata it was:
400 + 85*TL + 4.5*85*(TL-59) = 467.5*TL - 22167.5

and if you just straight extrapolate the values it could now be:
53960.5 + 394.36*TL + 4.5*394.36*(TL-59) = 2167.5*TL - 158167.5
or
45095.5 + 394.36*TL + 4.5*394.36*(TL-64) = 2167.5*TL - 158167.5
or something totally different

Well, after doing some reading into the LibStatLogic-1.2.lua file in Rating Buster, I think I found the lines of coding your looking for. This is found in the "GetReductionFromArmor(armor, attackerLevel)" section of the file:

local levelModifier = attackerLevel
  if ( levelModifier > 80 ) then
    levelModifier = levelModifier + (4.5 * (levelModifier - 59)) + (20 * (levelModifier - 80));
  elseif ( levelModifier > 59 ) then
    levelModifier = levelModifier + (4.5 * (levelModifier - 59))
  end
  local temp = armor / (85 * levelModifier + 400)
  local armorReduction = temp / (1 + temp)
  -- caps at 0.75
  if armorReduction > 0.75 then
    armorReduction = 0.75
  end

Was working on a spreadsheet to calculate some DR numbers, and noticed a problem.

Using the avoidance formula:

$\frac{1}{x'} = \frac{1}{c}+\frac{k}{x}}$

With a value of 9.27% and DK constants:

$\frac{1}{x'} = \frac{1}{65.631440}+\frac{0.9560}{0.0927}}$

Solving the equation for $x'$ yields (rounded to the 5th decimal):

$x' = 0.09682$

Which is greater than the original 9.27% I started with.

I don't see it being noted anywhere (in this thread, on wowpedia) that DR is inverted at certain points. Is this an error with my math, or am I just wrong?

Tharia · 03/01/11, 7:25 AM

You need to put in 9.27 for x instead of 0.0927, then x' = 8.45

Thanks, that would explain it.

Maybe it would be worth (subtly) clarifying it in the OP? Unless I am mistaken, percentages are usually stated as 1 being 100%, etc.

This is probably a really dumb question but in the dodge/agility table, should I assume the first column is base dodge, not base agility?

Hi, does anyone know where I can get the attack speed/unmitigated melee damage for Cataclysm raid bosses? I have looked on these boards as well as elsewhere and have not been able to find this information, despite the fact that it has a substantial effect on appropriate stat weights. I am using Tangedyn's spreadsheet (posted in the bear thread) but I have no idea how accurate its default values are.

You can get the current attack speed of your target with the following macro:
/run local sp=UnitAttackSpeed("target"); SendChatMessage(GetUnitName("target").."'s current attack speed: "..(("%%.%df"):format(2)):format(sp), "SAY");

Generally it is 2.0 for any boss that doesn't dual wield and without haste/enrage buffs.
You could also simply look through various World of Log fights and use the Expression system to filter only for boss hits. That's probably the only way to get the damage range as well, though you have to consider armor and debuffs then.

Thanks for the macro. I have tried it and gotten 1.8 attack speed though not 2.0.
