So Khat that is pretty awesome.
So with a DK you want to get your diseases up and keep them up so you could do something like.

1. /castsequence reset=target Icy Touch, Plague Strike, Death Strike x 4 (gets diseases up, makes death runes etc)
2. /castsequence reset=combat Blood Boil, Heart Strike x4 (burns up blood, pestilence for AOE, powerful strike etc)
3. /cast Rune Strike (runic power dump)
4. /cast 30 second cool downs AMS, Blood Rune etc etc

Keep my procs on manual buttons and fire them when quartz master tells me to.

So I have two other questions.
1. Does someone have a blood/dk sequence I can look at or can you critique mine?
2. How often do I push the key just spam it or like once a second?
Thanks
