using Talent Calculator - World of Warcraft as a spec, and using the following rotation:
Build without Reaping

PS – IT – BS – BS – SS – DC – HoW

SS – DC – BS – BS – SS – DC – (DC)

has me losing my diseases in the middle of my 2nd DC cast of the 2nd segment.

I'm asking how this rotation can possibly be correct if i've had this result for the past 2 hours on a dummy?

@Kaienn: Likely an oversight. Using two Blood Strikes on the second part of the rotation adds a global compared to the Reaping rotating where you simply use SS. If you add up all of the GCDs used in a non-reaping rotation, you'll end up with essentially no time to spare at the end of the 21 second disease durations to refresh them before they fall off.

A high enough amount of haste might let get get away by the skin of your teeth (due to reducing the GCD evoked on IT and DC), but that's pushing it.

With 0 haste rating my diseases don't expire before being refreshed. You are doing something wrong.

edit: Correction, they sometimes fall off exactly as I refresh them.

I've looked around for info, but I have yet to find any.

Is anyone aware of an in-game combat parsing mod that tracks the 2 SS hits separately?

I suppose I'll start looking and get back to you all if I find one worthwhile. If anyone can save me some time, it would be appreciated. =)

Same spec and rotation. I do use AutoHotkey to spam keypresses, I suppose that could be adding up to a GCD over the course of the rotation.

I'm using miks scrolling combat text, and you can see the two separate portions of the SS.

On the front page the OP mentioned that there may be times where you have to waste rp, as the DCs will not be worth slowing the rest of your rotation. If this is the case, can the 2 points in dirge be used as free points? I was considering putting them either back into Dark Conviction, or possibly into IUP. I only suggest IUP as my personal raid duties include a lot of running around with the exception of Saurfang.

14 unhasted GCDs take 21 sec to execute even before accounting for network latency. Theoretically this refresh would be by the skin of your teeth even with very high haste and very low effective latency unbuffed; without any haste at all it ought to be theoretically impossible (the theory would, of course, be proven wrong if your data is accurate).

Are you sure that nobody in your group had a WoA totem down through the "unhasted" rotation test? If you were indeed able to do this completely unhasted (even sometimes), then that would suggest that some kind of "latency leeway" like for non-instant spells might have been added to instants, which would obviously warrant further testing.

Im also trying to find a way to make Morbidity possible in my single target spec. 5/5 BA 2/3 Morb 3/5 Necrosis and of course no reaping seems to be a little better than your above set up from my minimal testing...especially aoe wise.

It was totally unbuffed except Revitalize (for RP) on a training dummy with 50ms ping. Diseases get refreshed about .3 seconds before or after it would expire.

I was wrong about the 0 haste test, another DK and my timers made a fool of me. Outside of that you only need a bit of haste to overcome your ping and you're fine.

Looking at who you were hitting, it was general trash mobs, right? Did you apply your diseases? Remember, the shadow portion is based on the diseases you have applied- the 75% extra is only with 3 diseases up.
