I have broken down all of the current masteries into two categories: unique, interesting masteries and flat bonus masteries.

Unique, interesting masteries:

Flat bonus masteries:

Why this mastery is interesting
The flat increase to block chance may be boring, but this mastery also gives prot warriors the chance to critically block, which allows them to block double the amount of a normal block. It doesn't take long to realize how powerful that is, and seeing as how there is no other way to get a critical block other than with this mastery, it becomes very unique.

player: 20! I critically block!
GM: ...what?

80 mastery rating will then make you critically block every melee attack then?

At level 80 at least the only thing you gain by picking more mastery over more avoidance is that it's more consistent, but ilvl point for ilvl point avoidance is much better until possibly very late game when the diminishing returns makes this false.

Kinda surprised that no one has posted this yet, but...
How do you figure out what your active critical block % chance is? And does shield block increase your chance to critically block even if it doesn't push you over 100% avoidance?

And on another topic, why don't critical blocks generate critical Shield Specialization Rage? Get on that, Blizzard.

For those looking for some theorycrafting:

A normal block reduces damage by 30%, a critical block reduces damage by 60%.
Your critical block chance only applies to attacks that you would have blocked anyway.

Critical block double-dips into Mastery, so the more you have, the better it gets (until you block cap and completely push normal hits off the combat table).

Each point of Mastery gives you 1.5% increased block chance and 1.5% increased critical block chance.
You get 8 points of Mastery and 5% block chance base, and 15% increased block chance as a Protection Warrior from Sentinelle inébranlable, giving you a base block chance of 32% vs. a level 85 attacker. By Mastery I mean actual value (including the 8% base), not rating.

Ignoring misses, dodges, and parries (so only considering blocked and direct hits) from a level 85 attacker (nb: raid bosses are level 88):

Block chance (CB) = Mastery * 1.5% + 20%.
Critical block chance (CBC) = Mastery * 1.5%.

Chance of an attack being critically blocked = BC * CBC = (M * 1.5% + 20%) * (M * 1.5%)
Chance of attack being non-critically blocked = BC * (1 - CBC)
Chance of attack not being blocked = 1 - BC

Damage mitigated by a critical block = 60% reduction
Damage mitigated by a block = 30% reduction
Damage mitigated by a normal hit = 0% reduction

Damage taken based on Mastery:
Unblocked hits = 1 - BC * 100% = 1 - (M * 1.5% + 20%)
Block damage = BC * (1 - CBC) * 70% = (M * 1.5% + 20%) * (1 - M * 1.5%) * 70%
Critical block damage = BC * CBC * 40% = (M * 1.5% + 20%) * (M * 1.5%) * 40%

Total mitigation by Mastery:
BC * (30% + 30% * CBC) = (M * 1.5% + 20%) * (30% + 30% * M * 1.5%)
= (0.015M + 0.2) * (0.0045M + 0.3)

What does this tell us?
This is a quadratic equation, thus mastery has ever-increasing returns. This is the opposite to the diminishing returns of Parry and Dodge.

NB: At 20 Mastery, Maîtrise : Blocage critique will mitigate more damage than Paladins' Maîtrise : Rempart divin.
NB: these calculations ignore other effects, e.g. , Maîtrise du blocage and the shield block metagem.
NB: block (soft) cap happens when block plus avoidance (chance to miss, chance to parry, chance to dodge) exceeds 102.4% vs. a level 88 raid boss.

Sample values (Mit refers to overall damage taken):

M BC CBC B Mit CB Mit Mit
0 20.0% 0.00% 94.00% 100.00% 94.0%
8 32.0% 12.00% 90.40% 92.80% 89.2%
10 35.0% 15.00% 89.50% 91.00% 87.9%
15 42.5% 22.50% 87.25% 86.50% 84.4%
16 44.0% 24.00% 86.80% 85.60% 83.6%
17 45.5% 25.50% 86.35% 84.70% 82.9%
18 47.0% 27.00% 85.90% 83.80% 82.1%
19 48.5% 28.50% 85.45% 82.90% 81.3%
20 50.0% 30.00% 85.00% 82.00% 80.5%
21 51.5% 31.50% 84.55% 81.10% 79.7%
22 53.0% 33.00% 84.10% 80.20% 78.9%
23 54.5% 34.50% 83.65% 79.30% 78.0%
24 56.0% 36.00% 83.20% 78.40% 77.2%
25 57.5% 37.50% 82.75% 77.50% 76.3%

Please highlight any logical/calculation fallacies.

I don't have the wowhead cred to post replies, but regarding the above comments on blocking magical attacks, it's actually funny that inferno blade is mentioned. Because that, and some other magical attacks (melee attacks from elementals which are BOTH resistable and blockable come to mind - from my sarth 3d progression) ARE actually blockable, both by paladins and warriors. In addition, it's worthwhile to keep in mind the value of Bastion de défense, which was also unmentioned, as a way of dealing with magic damage - which is still relevant to the block conversation here.

Question: Its my understanding that mobs (not pvp) never critical strike they instead do a "Crushing blow" type hit. I am going by blizzards notes.

Does critical block work against mobs with crushing blow or do mobs critical hit now?
I cant find any notes on it from blizz.
Any info would be appreciated.

thanks
Kay
