First off let me say that I have extensively gone over nearly every thread on these forums. The issue I am having is that most threads that give concrete evidence on threat rotations, tend to be severely outdated or have lots of posts contradicting what the thread says.
This post has wrong information. The best possible rotation is Shield Slam + brainless Devastate spam, for a more detailed calculation see my post below.
My own calculations state otherwise.
I just logged in after a 4 months break, and saw Devastate changed. I reprogrammed my old special ability simulator with the new values and filled in my stats. These are the results:
Attack Power: 3800;Block Value 1400:Critical Strike 7%;Expertise 8.5 %; Weapon:
Speed 1.6; DPS 188.1; (Sorthalis) Talents/Debuffs/Glyphs:
Improved Revenge, Impale, Mongoose (average over time),Glyph of Devastate, Mange/Trauma, CoR/Faerie Fire
Note that these threat values are calculated off unbuffed stats. Concussion Blow and Shockwave scale better than Devastate and thus will out-scale Devastate further in a raid-buffed scenario.
The conclusion is that the ideal cycle has not changed much. Now, you want to use your long CDs (HT,SW,CB) before your Shield Slams comes off the cooldown instead of just queuing them after Shield Slam as soon as they come off the cooldown.
The best threat cycle changes from:
Priority cycle pre Devastate buff:
1. Shield Slam
3.1 Heroic Throw 3.2 Shockwave 3.3 Concussion Blow 3.4 Devastate
4. Thunder Clap
to: Priority cycle post Devastate buff:
1. Shield Slam
4.1 Heroic Throw 4.2 Shockwave 4.3 Concussion Blow
You read this priority cycle like this: If you get a S&B proc you just start the cycle over again and do the highest threat move; so if Revenge is on CD use Devastate.
Your second move after you shield slamed (it does not matter if was a S&B proc or not) should be a threat move off number four (4.1 Heroic Throw 4.2 Shockwave 4.3 Concussion Blow); if these are on cooldown, just start the cycle again and do the highest threat move.
Yomo,I pulled your stats off the armory and using Wartotem's spreadsheet unbuffed I found that the Results were:
Not to mention that you are going to have to be completely buffed for Shockwave to even stand a chance it surpassing Devastate in a raid situation and that is not even including the chances you get Sword and Board from Devastate. The Sunder Armor debuff is also crucial to be kept on bosses.
This shows that either you or Wartotem's spreadsheet is wrong. Are you sure you are including Glyph of Devastate and the T8 set bonus in your simulator, they both increase Devastate's threat value by a large amount, Without those though Devastate still out threats Revenge by a couple hundred TPS though.
Devastate scales better than Revenge as well, which matter a lot with raid buffs.
I've just entered my Warrior's current stats in the spreadsheet and fully raidbuffed I got:
4700 AP, 1761 block value, 14,3% effective crit, 20 expertise
Using ToC sword (1.5 speed, 163 DPS)
Using same talents/Glyphs as you, except I have Deep Wounds & Blade Ward enchant.
So overall Devastate just beats cooldowns, but at the cost of a lot of DPS. Revenge for me is just a DPS tool if I can afford the threat, but I usually do not spec for that. I didn't include S&B procs btw.
I think the biggest difference here is Deep Wounds, which favors Dev/SS more cause of talents. But as I've seen up to 800 TPS increases from just speccing this talent, I do not consider any discussion about threat valid if you don't spec Deep Wounds. It blows every other possible threat talent out of the water (except maybe that 1 point in Devastate).
Edit: Damn you krc, if I wasn't running bloody errands all the time ...
Shockwave can be better than devestate depending on your hit rating, expertise rating and wether you have 2pc t8 and/or 2 pc t9. You really cant say 1 is better than the other any more, its extremely gear dependent.
Also improved revenge is pretty useless now. Its only good for very low rage situations or if you need the stun.
Improved Revenge is mostly a DPS tool, as you only use it if you can afford the loss in threat compared to Devastate and the stun on your target reducing it's avoidances to 0%. And if the target is stun immune it's usually a raid boss, where you don't care about the Rage anyway
Edit: @Yomo: Cooldowns are still pretty good as they provide substantially more DPS for only a small threat loss.
Then add Talents; 15 % sword and board crit (other talents are the same for Revenge or other abilities (10% modifier))
990+ (2414.72 * 1.15) = 2776.93 + 990 = 3766.93
It's worth noting that with most prot builds, impale is included as well, which will add damage to crits for both devastate and revenge, but given that devastate will have a higher base crit chance (even before any set bonuses), this will favor devastate further.
Also, with deep wounds, the higher crit chance for devastate will result in more overall damage/threat being added to the calculations.
