ROTATION

OB>OB>HS>HS>DC
HS>HS>HS>HS>HS>HS>DC

Use sudden death procs between HS's to increase damage ouput.


DAMAGE RANGE

With current numbers on PTR using [Betrayer of Humanity] and 5000 AP (Raid Situation):

HEARTSTRIKE

With Glyph of BS / Bloody strikes

(((758) + (3.3 * 5000 / 14))*0.6)+220.8)*1.2)*1.3 = 2157.07 Base damage 2351.21 with Bloody Vengeance.

With Glyph of BS / Bloody strikes / [Sigil of the Dark Rider]

(((758) + (3.3 * 5000 / 14))*0.6)+243.8)*1.2)*1.3 = 2192.95 Base damage 2390.32 with Bloody Vengeance.


OBLITERATE

With Glyph of OB

((758) + (3.3 * 5000 / 14))*1)+292)*1.2 = 2674.28 Base damage 2914.96 with Bloody Vengeance.

With Glyph of OB & [Sigil of Awareness]

((758) + (3.3 * 5000 / 14))*1)+502)*1.2 = 2926.28 Base damage 3189.65 with Bloody Vengeance.


So the damage from both sigils is 50% on extra damage and 50% on extra disease damage but the [Sigil of the Dark Rider] does NOT add 90 damage to HS at level 80 but 45 damage... I don't know why but it means that [Sigil of Awareness] has more value with OB*2 than the HS increase (even on a 8*HS rotation).

DAMAGE LOST FROM NO DISEASES

I AM NOT TAKING RAID BUFFS/DEBUFFS INTO ACCOUNT.

From 2951.93 (HS damage with diseases) we drop to 2351.21 (HS damage without diseases)
And 3846.26 (OB Damage with diseases/Sigil) we drop to 3189.65 (OB damage without diseases/with Sigil)

Now the damage lost from Frost Fever and Blood plague is:

((5000*0.055)/3)*2 = 183.33 dps (91.66 per disease)

The damage lost from IT is:

(5000*0.1)+236 = 736

The damage lost from PS is:

((758) + (3.3 * 5000 / 14))*0.3)+113.4) = 466.97

DAMAGE PER ROTATION

So let's get this started shall we?

736+466.97+(2951.93*2)+3846.26 = 10954.09 + 65 RP
736+466.97+(2951.93*4) = 13010.68 + 70 RP

For a total of 23963.77 damage to which we can add (14.5*91.66)+(16.5*91.66) = 2841.46 damage and 3.375 Death coils from RP gain that deal ((5000*0.15)+443)*3.375 =4026.375
Grand Total damage: 30831.605

On the other hand we have (3189.65*2)+(2351.21*8)= 25188.98 and 2.75 Death coils from RP gain.
Grand Total damage: 28469.73

HYSTERIA SCALING

Adding hysteria to the no disease rotation as a permanent 3.33% increase to damage (since it's a 100% physical rotation). While the disease rotation does not gain hysteria increase except on 22491.77 damage.

No Disease Rotation scales much better with hysteria.


No disease rotation with hysteria:29409.23
Disease rotation with hysteria: 31101.83

CRITICAL STRIKE SCALING

Now assuming I am hit and expertise capped and that I have 50% critical strike chance on OB and HS (not extremely hard to achieve) and that the bonus damage of HS/OB is 222.5%
((1.00 - 0.5) + 2.225 * 0.5)= 1.6125 or 61.25% damage increase.

So no disease rotation goes from: 29409.23*1.6125= 47422.38 damage.

While the disease rotation receives: 22269.23*1.6125= 35909.14 damage.

Then I only have 200% damage on IT/PS/DC and 41% critical strike chance with them:
((1.00 - 0.41) + 2 * 0.41)= 1.41 or 41% damage increase.

So IT/PS: 2405.94*1.41= 3392.37damage

DC from disease rotation: 4026.375*1.41= 5677.18 damage.
DC from No disease rotation: 3280.75*1.41= 4625.85 damage.

So the Disease rotation has:
5677.18+3392.37+35909.14+2841.46 = 47819.67 total damage.

And the No Disease rotation has:
47422.38+4625.85= 52048.22 total damage.

No disease Rotation scales much better with critical strike rating than the disease rotation.

BLOOD CAKED BLADE

So far the No disease rotation is ahead.
But for the numbers to be correct I need to come to BCB and the loss of two diseases on BCB damage.

I said we were using [Betrayer of Humanity] and 5000 ap so a 3.4 weapon speed with 758 weapon damage.

So with the no disease rotation BCB would be dealing:

(758+((5000*3.3) / 14))*0.25= 484.14 damage per proc

With the disease rotation BCB would be dealing:

(758+((5000*3.3) / 14))*0.50= 968.28 damage per proc

On a 16 seconds rotation using a 3.4 speed weapon BCB will proc:

(16/3.4)*0.3 = 1.41 procs.

So the no disease rotation would be dealing:

484.14*1.41 =683.49 damage

The disease rotation would be dealing:

968.28*1.41 =1365.27 damage


FINAL OUTPUT PER ROTATION

The final numbers are:

NO DISEASE ROTATION: 683.49 + 52048.22 =52731.71 damage per complete rotation.
DISEASE ROTATION: 1365.27 + 47819.67 =49184.94 damage per complete rotation.


So a no disease rotation works just fine. In fact it scales better with gear than a normal disease rotation.
Most Blood Dk's easily reach 50% and more Cc on OB/HS in a raid environment.

Depending on gear 51/0/20 is played with or without diseases.

With high levels of gear the no disease rotation offers higher returns in general but on AOE fights the extra 2*HS per rotation widen the gap.
Using the no disease rotation also allows to pick up 3/3 virulence and be spell capped with 264 hit rating (considering Sp/Draenei in your raid). Futher increasing dps on Death Coil.
