Old stuff
Does anyone know what the damage reduction from armor is? I know it changes across levels but someone must know the formula...
- Damage-Reduction = armor / (armor + 85*level + 400)

+Defense can actually reduce crushing blows
Theoretically you can actually reduce the chance of crushing blows (indirectly) via defense, because if you have enough of it you can get your Dodge, Parry, and Block stats high enough to push Crushing blows off the Attack Table. Although not via the same mechanism, it's important to not be misleading in the fact that there's some sort of "defense cap".
shadok posting: I woul like to ask a few questions about defense that i'm unable to test myself. First the defense cap that is mentionned on different sites; is it just the defense level that prevent all posible crit from bosses, or is it a real cap where defense stops reducing damages in any ways?
My second question is does defense increase glancing blow rate. Indeed if you just take the dodge/block/parry/miss chance that gives def, you will find that pure dodge or parry rate is better in pure damage reduction. Altough when you try it it seems that defense reduces the damages way more. From my own experience i would say it is due to an increased glancing blow rate and an increased glancing blow effect, however it is impossible to find on the net a serious test made to calculate it.
And i dont see what you mean about the crushing blows. even if your parry miss dodge rate prevents a lot of attacks on you, the remaining attacks will always crush at the same rate. There is no reason for parry dodge ans miss to apply preferentially on a crushing blow.
Cleanup
Something the article isn't too clear on:
A level 73 boss v a level 70 player tank. Does the boss still have a 5% Crit chance v the player, or is it increased due to his skill being 365?
For a druid to become crit-immune with Survival of the Fittest (-3% Chance to be crit) leaves the NPC at 2% Crit chance: 365 - 415 * .04 = -2 which means 415 Defense is needed by a feral druid to become crit-immune for a skullboss.
Would appreciate it if someone could just confirm that for me, and I can maybe work on making the article a little more clear on this. Furiousv 17:14, 31 December 2007 (UTC)
A 73 boss starts with a 5.6% crit chance against a 70 player with max defense. In the absence of resilience, 415 is the target defense for feral druids Thoth 19:13, 16 January 2008 (UTC)
arithmetic error
In the "2.0 changes" section we have this text:
For a level 70 : 2.36 DR = 2 41/112 DR = 1 defense skill
The arithmetic is wrong. 241/112 = 2.15 while 241/102 = 2.36. Can someone dig up a URL with the formula for all levels, plus fix whichever number is wrong? (so far the 241/102 is corresponding with my test data better).
Thoughts on Math: I believe they are saying it is a mixed fraction meaning 2 + (41/112) DR = 2 + 0.36607 DR ~= 2.367 DR... or rounded down to be 2.36 DR.
Tank rating script
/script DEFAULT_CHAT_FRAME:AddMessage(2.6-(GetCombatRatingBonus(CR_DEFENSE_SKILL)*.04+GetCombatRatingBonus(CR_CRIT_TAKEN_MELEE)),1,0.5,0)
Is that script still accurate? and does it work for all classes? Zurr T ∙ C 02:26, 22 January 2008 (UTC)
I don't understand where the 2.6 comes from. Looking at the Combat rating - Resilience page, it seems to be in relation to feral druids with the survival of the fittest (SotF) talent. Should this not be 5.6 for tanks which don't have the -3% crit against chance given by SotF? I believe 5.6% would come from:
- 5% crit chance for all mobs of equal level (from Defense page), and
- and 0.6% crit chance for the extra 15 weapon skill a lvl73 will have against a lvl70 (0.04 crit/weapon skill).

Stuff from T:Formulas:Defense
On the main page I submitted a more precise number for defense skill-per-rating; here, I offer the data from which I derived that number. The first column is taken directly from the character sheet with different gear combinations; the second column is taken from the "GetCombatRatingBonus(2)" API function in-game. The output of this function appears to be floating point, which only allows for a certain number of significant digits; this is why the decimal precision drops as the number of non-decimal digits increases.
Please note that WoW only considers Weapon and Defense Skills as integers, which are rounded down, which means there is no change to miss, dodge, etc from 12 to 14 Rating (for example), since both give only 5 Skill.

- Rounded down?! Does this mean that the Shield Block rating of 15 on Andormu's Tear which counts for +1.90% (@ lvl70) is rounded down to +1%? And what about things like Greater Inscription of Warding with its 15 Dodge rating? Doesnt that equate to some +0.8% (@ lvl70) to dodge? is that rounded down to 0? Surely not. What about on my character sheet where it says maybe +15.5% chance to parry, is that rounded down? Or does the rounding only occur with Defense Rating conversions and Weapon Skill Rating conversions?

- Originally, there was only defense skill on gear. The game is only coded to directly translate defense skill into dodge, parry, miss and block chance. Defense rating from gear is converted into defense skill by a formula based on level, and that amount of defense skill can only be an integer. As such, any extra defense rating is rounded down and provides no benefit at that particular time. WoWWiki-Sakkura (talk) 15:00, 4 September 2008 (UTC)
Base defense value 350 or 370
The page consistently speaks about the base defense capped at character_level * 5 => 70*5 = 350 at level 70, but my level 70 draenei warrior has a defense skill of 370 (in the actual skills table). Since 490 is the aim regardless, it's not a big deal, but I wonder at the difference.

It's because you have the anticipation talent. Anticipation adds 20 defense to the base defense, so the base will appear as 370 in your tables.
