I'd gladly compile everything and forge it into a proper guide, if you guys wanted. I'd just need a few days (and maybe a helper or two) to sift through the thread and get everything.
What are the numbers on Shield Block and Barrier after all these changes and with an avoidance build, concerning mitigation and smoothing?
I find that on Garrosh for example my health will be more stable if I spend more rage on Barrier, that's anecdotal evidence though. Perhaps it is because Barrier will give you more value upfront, while Shield Block's value is strewn over 6s? I feel more in control of my health % by just popping barrier when I am in danger, i.e. < 60% hp.
Haven't tanked Garrosh on my war yet so my guess would be to swap to SBar in p2 at 1-2 dot stacks.
Armor reduction, Vengeance and Stamina play quite an important factor.
The higher the armor reduction the more beneficial the reduction of barrier will become. That is because it is an absolute reduction and no percentage reduction like block.
Mostly in an avoidance build you are low on mastery thus a 60% block can not be counted on.
Lets assume we are encountering a hard-hitter.
3,000,000 damage every 1,5seconds
65.00% Armor Reduction
block = 30%
crit block = 60%
20rage barrier = 46%
40rage barrier = 91%
60rage barrier = 137%
You can even combine both.
But as you can tell already...if you do not crit-block and are sitting on high armor a simple barrier can be >45% reduction. The more rage you put in the barrier the more it will absorb.
Important...the reduction on barrier is bound to your Vengeance until your fall under the stamina part of the shield barrier formula. Thus if your armor reduction is static you keep the 46% reduction for the full Vengeance range. Same goes for block.
Shield barrier is veeeery good, but you need to take that with a grain of salt. A block will safe you for 6 seconds.
A barrier will just eat up one hit. You may be lucky and get a Revenge/SS in the global and get another 20 rage for a new barrier but that cannot be kept on forever and normally you do not want to be catched without any sort of mitigation ever.
I would use block all the time and on block downtime use barrier/demo.
But...as Theck mentioned in one of his writeups. If you already took a large hit you may need to buy your healers time to get you back up. A block may not safe your ass, but a barrier can.
But in the end it is close.
A 60rage barrier = 137% reduction. Over 6 seconds and if you assume 4 enemy hits (aka 1.5sec hit timer) block will add up to 120-240% reduction. If you can gain over 80 rage in 6 seconds you could do a 60 rage barrier and a 20 rage barrier netting you 183% reduction over the course of 6 seconds. Getting 80 rage is not impossible with all the enrage procs nowadays.
Slow enemy hits+hard hits = 60 rage barrier
Fast enemy hits = block+barrier
On the damage done front you probably want to optimize HR buff uptime.
Well if you're so low on vengeance that stamina is the deciding factor for SBar you generally don't need to worry about reducing damage anyway -> Shield Block all the way.
Also those numbers are completely inflated.
65% armor is insane - that's like 85k armor
600k vengeance also completely inflated - the only fight I'd get close to that is the slow stacking dot on normal IJ - everything else with that magnitude of damage will kill you period.
I edited my text. Vengeance doesn't matter. Once you surpass the stamina part on the barrier formula the values flat out on a percentage that is based on your armor reduction. You are right for armor reduction but Sco is already at 63% with ilvl 570.
If you assume 62% armor reduction (even I have nearly 61%) your barrier values will be 42%, 84% and 126%. That is not a big difference.
200k Vengeance scenario:
The benefit of Shield Barrier is that you "could" spend 80rage per 6 seconds on defense. Shield Block cannot do this for you. You can only spend 60rage per 6 seconds (with later gaps of 3 seconds). The more rage you have left over the better Shield Barrier becomes damage taken wise.
What you want to use depends on the encounter your are playing, the build you are playing (avoidance vs. mastery) and the situation your are currently at health-wise (big hit incoming?, etc).
Can you post the formula for that? I know that miss/parry/dodge change by 1.5 per level but how do you calculate armor reduction?
What you wrote would have quite an impact on Shield Barrier (for physical damage, aka damage affected by armor reduction).
DR% = Armor / (Armor + 400 + 85 * AttackerLevel + (4.5 * (AttackerLevel -59)) + (20 * (AttackerLevel - 80)) + (22 * (AttackerLevel - 85)); )
Simplified, the formula becomes: DR% = Armor / (Armor + (467.5 * AttackerLevel - 22167.5))

Flawless - Go casual or go home.
lvl 90 138,773 armor 75%
lvl 93 175,110 armor 75%
so what does 75% armor reduction mean? It means you only take 25% or 1/4 of damage thus your EH is 400% of what it was.
This means that 175110 armor increases your EH by 300% or 175110/3 (some 57kish) increases your EH by 100% (and is thus equal to the base armor against a 93 target)
Then you calculate 1 - base/(base + 70k) to see how much damage reduction you get at 70k armor.
Or you calculate base/.35 to find out how much 'total' armor you need for 65% reduction or (base/.35)-base to find out how much actual armor you need.
going from 60% to 64% damage reduction means going from 40% to 36% damage taken which is a damage reduction of 10% or in other words you need 1(1-.1) -1 = 1/9 ~11% more total armor (that is from your current armor plus the 50kish base) to get from 60 to 64% (which is more than 10k armor)
Re barrier vs block: I run block unless it is on cd or I have just taken a large spike or the non blockable damage starts to way exceed the blockable damage. This is an aspect of prot warriors that make us so fun. It is not mindless blackout kick spam. We can make decisions during the fight with trade offs. Same with our gearing. There is no cookie cutter way to play prot in 5.4. Just communicate with your healers. Prot is in a great place with play style, raid utility, dtps, and dps.
Thanks for the insight zorker. It appears that for avoidance builds, barrier comes ahead, but block is still very valuable.
Anybody using Avatar on any fight in particular? I've been using Bloodbath on pretty much every fight, apart from the occasional switch to Storm Bolt in case an add needs stunning.
Currently 1/14 hc (irl has screwed our raid team a bit recently so haven't had much chance to progress), but I was just wondering if Avatar was actually a better talent for any heroic fights.

*maybe* Norushen if you want to kill your add quickly inside
Possibly siegecrafter if you (for whatever reason) want to do more DPS to the shredder adds
Other than that, you really would be better off with bloodbath imo
Just killed Thok on 10 heroic last night, if anyone has any questions regarding how I played it, just ask !
guys, anyone have solo tanked Immerseus 10m.
yesterday i solo tanked and i think its nice idea to share, if this is a new thing
