Ievil's Blood Disease-less Spec sustain over 7000 dps on Patchwerk

hi guys, here is my current build, and when i say my, i am not in any way suggesting this is my creation, because it is not, but it is by far the best spec and rotation i have used since hitting lvl 80, this build comes from another site i visit often www.skeletonjack.com and this is his build, and he deserves all the credit.
not only does this build allow for tons of dps, and most likley (if the simple rotation is followed) will put you at the top of your raids dps meters, it is also a "rolls face over keyboard from left to right" mindless terror!!
try it out, im sure you will find it as sexy as i have! ;op
and here is the rotaion:

Rotation
OB -> HS -> DC -> OB -> HS -> DC

Yup, that simple. Now sometimes, depending on latency and the Rune CD thingymabob (where if you activate a Rune just after it came off of CD and it’ll start it’s CD at 8 or 9 seconds if used within 1-2 seconds of coming back) you can work in a 3rd DC at the end as well. YMMV.

You will end up hitting 100 RP at various points and be unable to dump all of it. That’s just a part of the spec. Get used to it. Always break up the HS/DC’s to take advantage of Sudden Doom procs. Making sure the HS’s are broken up so that no procs are over written by a new one is invaluable for your DPS. The very first rotation will not be able to fire off the first DC if you did not get a SD proc, but that’s fine. Just skip it. It’ll be there for the next one. Losing one DC to ensure that every single SD proc is used instead of wasted will net a DPS gain for you.
