And, for what it's worth, having free GCDs isn't a "problem" anyway, if you're expending all your resources and getting similar results-- it's actually pretty useful.
Agreed, I guess I was responding to the more recent posts suggesting a 10 second OB OB HS HS rotation.
In short, this is not to say that your rotation produces poor results. It's just that the diseaseless does produce just as good if not better results, and seems easier to execute consistently.
This I can almost agree with. I do think that diseaseless is very, very close (which is probably why it's getting nerfed in 3.1 according to GC). In cases of high connection or FPS lag diseaseless probably pulls out ahead.
I tried to compare my numbers to yours, but from your link it looks like you tanked Patchwerk.
Yep :/ Haven't been able to dps patch for the last couple weeks. Itching to try out my rotation with the shiny upgrades i got recently (especially greatness and betrayer).
The boss' armor doesn't really factor into the comparison, which is why it's not included in his math. Bonus damage to strikes from diseases is a flat amount, so the only change to the equation would be armor affecting the one OB vs. IT + PS + disease damage.
This is correct, but the physical damage reduction of even fully debuffed bosses is still around 30-35%, compared to ~4% spell damage reduction from the level difference resistance for spells, not to mention the spell damage increasing debuffs. I really doubt that it is possible to accurately compare one Obliterate with Icy Touch + Plague Strike + Diseases without looking at armor when one has a multiplier of .7 and the other ~1.1 (without an unholy dk).
With full raid armor debuffs and physical damage buffs, OB will still be competitive.
Competitive is a subjective term. Is the damage close? Yes, yes it is. Is it higher or lower though?
The length of the rotation is immaterial because they all last 20 seconds with rune cooldowns. It's all about the damage you do in those 20 seconds. If the fight has less than 20 seconds remaining, you should be changing up your abilities to squeeze in the maximum amount of damage anyway. The same goes for his Hysteria reasoning-- either rotation would benefit from prioritizing physical attacks while Hysteria is up, regardless of what your rotation normally is.
Rune cooldown times in either rotation are not static. They are reduced, seemingly magically, so that disease-based rotation does in fact take only ~18 seconds. I have not however been able to lower the duration of a diseaseless rotation to below 20 seconds, even while i was not using GCDs for anything other than oblit and hs. I was looking at the time between Obliterates in the disease rotation and the time between OB1 and OB 3 in a diseaseless rotation. This is somewhat difficult to show via a combat log screenshot, but anyone with timestamps enabled can go and check it out for themselves. So yes, rotation duration does matter, unless I'm doing something wrong.
