I still see questions arising about these two on these forums, so I figured I'd toss this up here for future reference.

If this already exists, please go ahead and nuke it :)

Defense is an armor attribute and modifying skill that allows a character to defend himself by using his armor effectively to reduce damage, and by avoiding or dodging attacks.

Defense Rating (DR) And What It Means

Instead of directly affecting Defense Skill (DS), items in TBC grant a bonus to Defense Rating (DR) instead. Skill bonuses are then calculated as follows:

For a level 60 : 1.5 DR = 1 DS

For a level 70 : 2.366 DR = 1 DS

Effects

For an attack from an equal-level NPC, each point in Defense Skill (DS):

Increases the chance of being missed by an attack by .04%

Increases the chance to dodge an attack by .04%

Increases the chance to parry an attack by .04%

Increases the chance to block an attack by .04%

Decreases the chance of being affected by a critical hit by .04%

This means that effectively, every 25 DS increases your chance to be missed, and to dodge, block, and parry, by 1%, and reduces your chance to be crit by 1%. Because all NPCs have a 5% crit rate against targets of the same level, against a level 70 player with 475 DS, a level 70 NPC effectively will not crit.

There have been unproven reports of still being crit by mobs while being Uncrittable, but as of yet, there is still no hard evidence to prove that a "minimum" crit chance exists.

However, a couple of the factors that might increase crit chances against you are:

-MCing a Feral druid

-Inherent increased crit chance (Shadow Labyrinth mobs)

-Broken gear

-Sitting down

-Defense-reducing debuffs (Emperor Vek'nilash)

At level 70, 350 is everyone's "base" defense value. To avoid Crits from Bosses (LVL 73 mobs) you will need a DS of 490 (125 DS is needed to negate the base 5% crit rate, plus another 15 is needed to negate the +3 level difference, 0.6%).

Due to the new talent Survival of the Fittest, Druids need only 65 DS (154 DR) extra to negate all critical hits, in other words 415 at level 70. Warriors and Paladin tanks are advised to continue aiming for the magical +140 (332 DR).

Crushing blows

In addition, DS decreases the chance of being affected by a crushing blow. Each point of DS will decrease the chance of being affected by a crushing blow by 2%. The benefit that defense will have on a crushing blow is limited by your level. In other words, increasing your DS will only reduce the chance of being struck by a crushing blow if your current DS value is below your level's maximum unbuffed value.

Resilience

Resilience is a rating which was created to reduce the effects of critical hits against your character. It has two components; it reduces the chance you will be critically hit by x%, and it reduces the damage dealt to you by critical hits by 2x%. x is the percentage resilience granted by a given resilience rating. Note that Resilience only affects Critical %'s, so if you're debating on which way to go, the best way to think of resilience is as a PVP rating. I prefer to use it as a Druid since it's quicker to get and I only see two of the benefits from Defense anyways.

Resilience bonuses are then calculated as follows:

For a level 60 : 25 Resilience = -1% Crit Chance and -2% Crit Damage

For a level 70 : 39.4 Resilience = -1% Crit Chance and -2% Crit Damage

Also a thing to note:

Defense and Resilience stack. So when determining how much of each you need to get to reach Crit Cap, look in your Character Sheet, click on Defense Tab, and add up the Percentages of Defense and Resilience.

Warriors and Paladins need 5.6% total.

Druids with SoTF need 2.6% total.
