Most of information in this thread is old (pre riposte). Avoidance is now the popular stacking do to 5.4 and riposte turning avoidance into crit, and crit giving us more rage and more damage. You'll find most warriors now stack avoidance despite mastery being the smoother stat/mitigation.

 

I even use a the IJ dodge trinket vs a 2nd stam trinket just for the dual bonus (trivial heal but also a bunch more crit via the dodge).

Not sure why this lie keeps getting perpetuated.

 

In my gear,

 

while shield block is down:

Avoidance rating is 261% more likely to reduce 10.75 times more damage than mastery rating.

 

while shield block is up:

Mastery rating is 22% more likely to reduce 48% less damage that avoidance rating would.

 

Which means that while you are least vulnerable (while shield block is up). Mastery technically does a better job of smoothing damage than avoidance (even though you take almost twice the damage). However, since no amount of gear can break 67% uptime on shield block, you're much better off gearing for when you are most vulnerable.

 

Even independent of the damage throughput argument, avoidance is a much better survivability stat than mastery.

Smoother ~= better. You do take less damage with avoidance mathematically over course of fight but mastery does provide a less spikey intake. Getting an unlucky string of hits where dodge/parry let you down is very dangerous.
 
So, while avoidance is a better mitigation stat, no one has ever argued that, mastery was always better for reducing spike damage and making damage intake more consistent. There is a reason a lot of warriors were using mastery build until 5.4 added riposte. I'm pretty sure theck had numbers on the comparison at one point or another. Riposte was basically a bandaid fix to warriors and DKs because they were avoiding avoidance. 

Also, assuming a 67% up time on block is also flawed. When me and theck simmed this, we factored in the average tank swap of 30 seconds (often even less on the harder fights, heroic garrosh you swap every 20-25). If most tanks swapped every 30 seconds during an encounter, then you actually sustained a greater up time on shield block. With charges regenerating during non tank moments, you can actually chain 3 shield blocks back to back (18 seconds straight) after a fresh taunt. I remember on grand empress taunts swapped often enough to have a near 100% up time on shield block while tanking the main boss. Garrosh you have 100% up time on shield block while tanking (unless you are using a gimmicky one tank strat).

Citation needed.

Heroic Garrosh is often solo-tanked, this point is largely moot. Even with 100% uptime on shield block, avoidance rating reduces twice the damage at 82% of the probability.

Probability of damage reduction does not necessarily mean you have an easier tank to heal. Taking the example to the extreme, 100% uptime on 1% damage reduction is not easier to heal than 90% uptime on 90% damage reduction.

 

EDIT:
A large reason that people tend to think mastery reduces spikes better than avoidance is a mis-representation of the piece-wise nature of warrior tanking.

 

In the simulations you'll often see people look at spike reduction over a certain number of swings

 

What follows are the worst case scenerios for 8 swing melees.

 

Case 1.
BBBBMMBB

Even naked you are taking only 77.5% of possible incoming damage (hooray shield block)

 

But your actual worst case is Case 2:
MMBBBBMM

85% of incoming.

 

So when people look at the effects of mastery on those streaks, even converting one block to a critical block pulls you below the 75% spike range.

 

However, that same rating budget, applied to avoidance instead of mastery, will take the 85% spike below a 70% spike more frequently than the mastery budget would take it to 75.

 

When you look at the smallest streaks avoidance much better at reducing the spikes (Even in bis gear, garrosh can still 2 shot you), and any streaks looked at above six are largely useless due to the cyclical nature of warrior tanking. This seems to always be overlooked when people are analyzing the spikiness of a tank.
