I was looking at the rotation section of this guide and i think its a bit missinformative.
First thing to say is that, since 245 sigil procs from every 2nd Death Strike, u should always try to do 1x DS and than spend 4x Blood/Death Runes.
Glyphs that you should be using are:
Disease
Death Strike
Dancing Rune Weapon
When it comes to the Ghoul DMG, its simply low.
Sure its better than Death Coils DMG (since u need 1 gcd to cast both), but its not anything mind blowing, meaning u should not prio Rise Dead over HS or DS during proc uptime...
So just use Rise Dead when u have free gcd instead of DC or save it for when u have to use Dark Pact.
Army of the Dead shouldnt be used at all. The only way when u can use it is 11+sec before combat (or to activate Rune Grace Timer as i explained in my UDK guide openers).
When it comes to DPS and rotation...
This is the rotation i found to be most usefull...
Opener:
IT > PS > DS > Hysteria > HS >
Blood Tap followed with instant /cancelaura Blood Tap macro >
HS > HS > Dancing Rune Weapon >
DS > HS > HS > HS > HS >
Pesti > HS > DS > HS > HS > DC > ...
Constant rotation should always be:
IT > PS > DS > HS > BT/cancelaura macro > HS > HS >
DS > HS > HS > HS > HS >
Pesti > HS > DS > HS > HS > DC* >
DS > HS > HS > HS > HS >
Pesti > HS > DS > HS > HS > DC* > ...
Use DC whenever u have a free GCD in btwn HS and DS spam, and just Repeat...
U dont need to use ERW since everything is perfectly synced.
The only way i find it usefull is in case u fk up something so u can fix it, or next time u use DRW and Hyst combined in same combat to maximise DMG of those 2 CDs...
When it comes to using DRW in the midle of a fight, i use it after my DBW proc again.
Its eather after i use: Pestilence > HS > DRW > DS > ...
Or before i do DS so i just go: DRW > IT > PS > ...
As for BiS gear, i think that the best stat gain comes from 5/5 T10, Toskz and TogC arp Cloak as Agility items, with the rest of items beeing standard Strength items.
Im not sure about the gear tho, but it does work a bit better than the Haste setup atm.
Il do some more dummy testing when i catch some free time.
Oh, i almost forgot, i finaly found where Blood DK is better than Unholy and Frost!
For clearing Zul Gurub while farming Mounts and those Swords for xmog...
Altho, Unholy in Frost Presence is nice aswell since u just let ur pets do the job, but il still give Blood upper hand here. :D
