Greatness has an average of 33% uptime.
I'm not saying that overlapping procs are impossible, I'm just saying that it has potential for doing more, but it requires buffs to stack.
To clarify further, I did the custom build DRW that had 51/2/18, but more points in necrosis and BCB compared to standard build with more ghoul.
The question about 51/0/20 vs 50/0/21 is which offers more usefulness. In both cases, using straight out DCs seems to win out on singletarget.
The usefulness of UB is that it's precastable, for example you can use excess RP to prepare it right before spawn (Mimiron and Freya comes to mind). And that it does AOE of course.

If a DRW without 2 points in frost lasts 16 seconds (glyphed), that means that if you keep on doing average DPS of 6k, it SHOULD do 48k damage per use. The thing is that it doesn't. There's issues with talents and stuff affecting it, and I can't say I noticed any fixes to that lately.
DKsim was updated about a month ago.

SO, maybe the calculator is horribly off, these s the results I get. It does result in that DC is a better use than DRW.

Also, on the rune usage, it's a set priority of HS and DS over DC in my sim. Priority is diseases up first and foremost, then heart strikes, then DS, then DC.
How DRW is implemented, you'd have to ask the author: http://elitistjerks.com/f72/t50274-k..._beta_0_8_4_a/

In theory, DRW has a 17,7% uptime, and with a 50% of damage done this would be 8,8% damage increase. That's not timing it with procs. The increase of damagei n death coils are correct, the question is, is the sim calculating the damage DRW does too low?
There's quite a big difference between 2% and 8,8%.
Because this is interesting, I will take my fellow DK, and have him do normal playing like we do, and one goes 51/0/20, and uses DRW, and one gowes our normal spec. We already have pretty identical specs, and pretty much same gear and DPS. Both have played Blood before wit DRW since WotLK launch.

*Edit* Creator of simulator posted, I'll leave the point on whether or not DRW calculation is correct to him-

Base crit would be interesting, should be 5% or 20%. Your theorycraft is correct, but ingame it's different. In my sheet DRW does not do enough damage, too (about 2%). On my two top 20 WMO Vezax kills DRW accounts for 4,7% and 5,5%. That is significantly more. I don't know why, but it's not that important. DRW is good anyway and scales of Str.

Trinket are not implemented right now, but DRW is used on FC proc. DRW should benefit of Hysteria once every two usage.
And of course, simulator wait to be at max RP to fire it.
ERW is not implemented. DRW disease damage are not calculated. But I don't think it is what is where the 6% missing damage are hiding.

Edit : DRW is implemented with 5% base critical chance

This is the big problem I have with sims, is people either incorrectly interpreting their results, or failing to evaluate the hypothetical against known data. DC doing more dmg doesn't make it a better use than DRW. DRW is always going to be higher dmg/RP then DC. The WWS I linked in the OP shows DRW as something like ~3.5% of my total for the whole instance, yet I don't DRW on trash, on boss fights it's typically closer to the 6-8% range. So 2% is clearly undervaluing it.

If DRW Disease damage isn't calculated I'm extremely perplexed as to why its average hit, according to Daeren's run, is only 877 damage. The average damage for the DK's Death Strike, Heart Strike, Death Coil and Melee swings are 6948, 6219, 5331 and 4572 respectively. Averaging those out we get 5892 average damage per attack. Effectively, DRW appears to only do 15% (877/5892) of the DK's damage in your sim. While we don't expect 50% due to talents, 15% is extremely low.

Straying a bit from the DPS comparisons, I have a question regarding the mechanics of the cleave on our Heart Strike. I assumed it worked the same as a warriors Cleave ability, except with 1 less target, but it seems I may have been wrong. Using Kologarn as the example, the DPS warrior in my guild was able to Cleave and hit both of the arms and the body, whereas if I use Heart Strike it will only hit whatever I'm targetting. We both stand directly in front of Kologarns beard, facing him, since you can hit all 3 targets from there. So what I'm wondering is if any testing or data is available that describes the range and arc of our cleave. It would seem that we have a narrower arc if his was cleaving and mine wasn't.

Ellitus- The problem your having is because of how your runes refresh. You should switch around your proposed rotation to DS, IT, PS, HS, HS, Dump, HS, HS, DS, HS, HS, Dump. The reason being, the only benefit DS gets from diseases is to the amount it heals you, so putting it in front of the rotation allows you to have two death runes refresh first, allowing the two HS's in the second half of the rotation. Try that out and I garuntee that the rotation feels alot better for you.

I have had the exact same problems with Kolo, I was not sure if it was because of our warriors WW/sweeping strikes as we have 2 MS warriors. I cannot position myself anywhere to cleave both the body and an arm. Does anyone know of a spot to hit both from?

I did some quick DRW testing tonight. I'm 99% sure DRW gets hysteria and inherits at least some talents.

Tested by comparing deathstrike damage, full DPS gear minus trinkets, [Giant Mace] (no runeforge), all deathstrikes fired with 3/3 bloody vengeance, abom's might, horn, and at least 26 RP. In every test where I used hysteria, hysteria went up before DRW. I only got a couple dozen DS's in before I got bored waiting on cooldowns so take this as anecdotal, but the [Giant Mace] has a really tiny damage range so big differences in damage should show up in just a few swings.

-In every test with a DRW DS crit, the crit was close to 250% of the average non-crit, which looks like Might of Mograine.

-DRW's DS's seemed to hit for 35%-40% of my DS's, with or without hysteria. Assuming DRW doesn't inherit your glyphs, and my data isn't off, then DRW probably has Improved Death Strike. This also seems to show that DRW's DS is getting hysteria.

-I'm seeing a significant difference in DRW DS damage with hysteria vs without. Without hysteria, my DRW's non-crit DS's ranged from 726-771. With hysteria up, the smallest was 907.


I'd guess that DRW has the major passive blood talents baked in. Besides MoM and Imp DS, it'd probably be worth testing Bloody Strikes if we could be sure how rune weapon's HS interacts with diseases. Also it looks like DRW gets hysteria on specials, although I'm not sure about white swings. It's entirely possible that DRW uses one set of rules to calculate specials and another to calculate autoattacks.

I did some testing last night with autoattacks and observed similar results. With melee swings in the ~1200 range going up to the ~1400 range once Hysteria was used. Somehow, I managed to overlook all of this when I did my first round of tests (I suspect I was casting Hysteria after popping DRW, instead of before).

We should definitely look into testing various other talents/abilities, particularly percentage based multipliers such as Blood Vengeance, Blood Presence and Tricks of the Trade.

Presumably it doesn't snapshot all your stats. Blizzard has stated repeatedly that there's a technical limitation preventing pets from scaling with some stats.

For what it's worth, I got some strange results initially when I started testing naked. My deathstrikes were in the 700 range, DRW's were in the 500s. The "DRW does 50% of your damage" thing is probably an approximation to make the tooltip cleaner - whatever formula DRW uses, I doubt the last operation is multiplying by 0.5. Most likely DRW gets a certain base swing damage and a percentage of your stats, just like every other pet in the game. When Blizzard nerfed DRW what they probably did was made that percentage much lower.
