A revision of how Devastate with Glyph compares to other threat abilities after it's recent buff.

Below math is wrong, due to me being a complete nabhead and not calculating in normalization as I should be.Thanks to bacchanal, Rashor, Hypatia & Kazey (and all others I missed) for taking the time to read all this and point out my mistakes. /bonk self!!

Note that the Deep Wounds math at the end is still relatively correct, but I will incorporate it into a new calculation/spreadsheet later on to keep it clear of this mess I made :P

Update:Complete spreadsheet is well on it's way and should be complete and ready for review somewhere this week.

Intro:

As most of you have read by now, Glyph of Devastate currently acts as if you do a Sunder Armor attack on top of the Devastate. With the recent changes to the damage of Devastate, I thought I'ld make a rough threat comparison with our other basic abilities.

Starting assumptions:

- A weapon with 1.6 speed has 300 average weapon damage and 1.6/14 = 11.4% AP scaling
- A weapon with 2.6 speed has 500 average weapon damage and 2.6/14 = 18.6% AP scaling
- Sunder Armor (ability) threat is 315 + 5% AP
- Devastate can be seen as plain damage + a Sunder Armor attack
- Glyph of Devastate adds a second Sunder Armor attack to Devastate
- All threat values not mentioned above are taken from http://www.tankspot.com/forums/f200/39775-wow-3-0-threat-values.html
- All numbers for Devastate are with the Glyph of Devastate.
- All abilities with +15% crit from talents are calculated as normal hit = average damage (crit damage and overall damage increases negate the boss armor). Abilities that do not have these kind of talents suffer a 10% damage penalty, noted as 'CL' for crit loss. This is a very rough number to make comparing damage and innate threat easier. The last equation containing “dmg” numbers is the one where damage and threat have not been added together.

Devastate = Damage + 2* Sunder Armor attackDevastate threat with glyph:

* Damage = Weapon damage + AP scaling + base damage per Sunder (debuff)

* Sunder Armor attack = 315 + 5% AP

Devastate = Weapon Damage + AP scaling + base damage per Sunder + 2*(315 + 5% AP)

For a 1.6 speed weapon this becomes

Devastate(1.6) = 300 dmg + (1.6/14 AP) dmg + 1010 dmg + 630 + 10% AP

Devastate(1.6) = 1310 dmg + (11.4% AP) dmg + 630 + 10% AP

Devastate(1.6) = 1940 + 21.4% AP

For a 2.6 speed weapon this is

Devastate(2.6) = 500 dmg + (2.6/14 AP) dmg + 1010 dmg + 630 + 10% AP

Devastate(2.6) = 1510 dmg + (18.6% AP) dmg + 630 + 10% AP

Devastate(2.6) = 2140 + 28.6% AP

Shield Slam threat & efficiency comparison:

SS = Gag Order * (base dmg + (actual) block value dmg) + 770 innate threat

SS = 1116.5 dmg + (1.1 * block) dmg + 770

SS = 1886.5 + 1.1 * block

Comparing to Devastate:

SS = Devastate(1.6)

1116.5 dmg + (1.1 * block) dmg + 770 = 1310 dmg + (11.4% AP) dmg + 630 + 10% AP

1886.5 + 1.1 * block = 1940 + 21.4% AP

1.1 * block = 53.5 + 21.4% AP

block = 48.6 + 19.5% AP

Example: 3000 AP Devastate(1.6) does as much threat as a 633 block value SS. At 4000 AP you need 828 block.

SS = Devastate(2.6)

1116.5 dmg + (1.1 * block) dmg + 770 = 1510 dmg + (18.6% AP) dmg + 630 + 10% AP

1886.5 + 1.1 * block = 2140 + 28.6% AP

1.1 * block = 253.5 + 28.6% AP

block = 230 + 26% AP

Example: 3000 AP Devastate(2.6) does as much threat as a 1009 block value SS. At 4000 AP you need 1267 block.

Comparing efficiency with 0/3 Focused Rage:SS = 20 / 15 * Devastate(1.6)

1116.5 dmg + (1.1 * block) dmg + 770 = 4/3 * (1310 dmg + (11.4% AP) dmg + 630 + 10% AP)

1886.5 + 1.1 * block = 2587 + 28.6% AP

1.1 * block = 700.5 + 28.6% AP

block = 637 + 26% AP

Example: 3000 AP Devastate(1.6) is as efficient as a 1416 block value SS. At 4000 AP this becomes 1676 block.

SS = Devastate(2.6)

1116.5 dmg + (1.1 * block) dmg + 770 = 4/3 * (1510 dmg + (18.6% AP) dmg + 630 + 10% AP)

1886.5 + 1.1 * block = 2853 + 38.1% AP

1.1 * block = 966.5 + 38.1% AP

block = 879 + 34.6% AP

Example: 3000 AP Devastate(2.6) is as efficient as a 1918 block value SS. At 4000 AP you need 2264 block.

Comparing efficiency with 3/3 Focused Rage:SS = 17 / 12 * Devastate(1.6)

1116.5 dmg + (1.1 * block) dmg + 770 = 17/12 * (1310 dmg + (11.4% AP) dmg + 630 + 10% AP)

1886.5 + 1.1 * block = 2748 + 30.4% AP

1.1 * block = 861.5 + 30.4% AP

block = 783 + 27.6% AP

Example: 3000 AP Devastate(1.6) is as efficient as a 1611 block value SS. At 4000 AP this becomes 1887 block.

SS = Devastate(2.6)

1116.5 dmg + (1.1 * block) dmg + 770 = 17/12 * (1510 dmg + (18.6% AP) dmg + 630 + 10% AP)

1886.5 + 1.1 * block = 3032 + 40.5% AP

1.1 * block = 1145.5 + 40.5% AP

block = 1041 + 36.8% AP

Example: 3000 AP Devastate(2.6) is as efficient as a 2145 block value SS. At 4000 AP you need 2513 block, which is within DR values.

Conclusion:With a slow weapon Devastate and Shield Slam will be very close together in threat (depending highly on your block value). In virtually all cases Devastate is more Rage-efficient than Shield Slam, even reaching into the DR values with a slow weapon and atleast average raiding gear.

Revenge:

Revenge = imp. Revenge * CL * (1615 dmg + (20.7% AP) dmg) + 121

Revenge = 1.2 * 0.9 * (1615 dmg + (20.7% AP) dmg) + 121

Revenge = 1744 dmg + (22.4% AP) dmg + 121

Revenge = 1865 + 22.4% AP

Revenge = Devastate(1.6)

1744 dmg + (22.4%) AP dmg + 121 = 1310 dmg + (11.4% AP) dmg + 630 + 10% AP

434 dmg + (11% AP) dmg = 509 + 10% AP

75 - 1% AP = 0

The turning point lies far below 0, in favor of Revenge. Only in specific case of high damage reduction is it worth redoing this calculation.

Revenge = Devastate(2.6)

1744 dmg + (22.4% AP) dmg + 121 = 1510 dmg + (18.6% AP) dmg + 630 + 10% AP

234 dmg + (3.8% AP) dmg = 509 + 10% AP

0 = 275 + 6.2% AP

Again we have a negative turning point, but this time in favor of Devastate.

Conclusion:

A fast weapon can never catch up to Revenge. A slow weapon on the other hand makes Revenge obsolete TPS-wise. Revenge is still far more efficient in all cases though.

Concussion Blow, Shockwave and Heroic Throw:

Concussion Blow = Shockwave = CL * (75% AP) dmg

Heroic Throw = CL * (12 dmg + (50% AP) dmg) * 1.5

With the exception of the amazing 12 base damage on Heroic Throw, all 3 abilities scale the same with AP, with no innate threat. I'll be comparing against Shockwave, but it will apply to all three.

Shockwave = CL * (75% AP) dmg

Shockwave = (67.5% AP) dmg

Shockwave = Devastate(1.6)

(67.5% AP) dmg = 1310 dmg + (11.4% AP) dmg + 630 + 10% AP

(56.1% AP) dmg – 1310 dmg = 630 + 10% AP

46.1% AP = 1940

AP = 4210

Shockwave = Devastate(2.6)

(67.5% AP) dmg = 1510 dmg + (18.6% AP) dmg + 630 + 10% AP

(48.9% AP) dmg – 1510 dmg = 630 + 10% AP

38.9% AP = 2140

AP = 5497

Conclusion:

Untill you reach 4210 with a 1.6 speed weapon or 5497 AP with a 2.6 speed weapon, Devastate wins in threat.

Final Conclusion:

With a slow weapon and a gear set with relatively low block value, Devastate pretty much beats all other GCD abilities TPS-wise. Shield Slam lies close enough to exceed that if you have some extra block value, e.g. from Glyph of Blocking.

Concerning efficiency you will want to keep using Revenge on the cooldown and use up S&B procs whenever you can.
