I looked at Swol in the armory (he's spec'd blood at the moment, so a good comparison). I noticed a few things:

1. The 23 agility for Flexweave Underlay was not being parsed. I've fixed that and it'll go into the next update.

2. I was under the impression that DKs get 1% crit for every 62.5 agility, which would give Swol 4.352% crit from agility, but the armory tooltip says 7.54% from agility...

3. The number being shown on the team robot simulator has 4.8% crit subtracted for the melee crit suppression against bosses.

So the armory thinks that Swol gets ~3.2% more crit from agility than the team robot simulator. I'll try to figure this out, but if anyone knows what the deal is, please let me know.

I'm going to post some changes that I hope will fix this... it seems to be an issue with different language/culture settings on people's computers. It's a little difficult to test though.

I've been trying this simulator out and it has helped me a bit optimizing my spec.

I changed it from a 0/53/18 DW build to 11/53/7 and it improved a lot in dps. But... I think it is mostly because the simulator might not be recording Blood-Caked blades correctly? I'm not sure but its a very very small percentage in the simulator with my gear, maybe it gets better as my gear gets better?

Also, the ratings the gems get are not a good guideline, it's always rating haste gem highest and actually it had expertise gem lowest even though I wasn't capped, I tried running with 2 34 expertise rating gems vs 2 34 haste in an item to compare it and the expertise always gave more dps.

Anyways, I'm new to this forum and thanks for this simulator.

I'm guessing you're probably right about your BCB getting better when you're gear gets better. It looks like the biggest thing is Bladed Armor is simply a really big buff to you right now. Running some sims on your character w/ full raid buffs, BA is adding:
18600 to autoattack
29870 to FS (including 3 more FS from Butchery RP)
32222 to Oblit (MH+OH)

Those three alone, not counting extra damage from diseases, Blood Strike, etc, add 80692 extra damage, whereas Necrosis + BCB add 74232. So that explains why the sim shows Blood is more DPS for you, but it doesn't necessarily answer if maybe BCB is hitting too softly or maybe Bladed Armor is granting too much AP.

Sigil of Virulence is rated higher and gives higher dps when I simulate than Awareness, will this change when my gear gets better, will Awareness become better at some point?

Have you made it so we can input engenieering enchants in yet? Both gloves, back and boots if you would please.

All in all very nice, but I do have some suggestions.

Physical miss % stays at 5% even when I'm capped. Very difficult to tell when I'm under hit cap. Other times I have seen this change, but I've never seen 0 miss chance even when capped. Just strange things going on in general here.

Is there a way to determine stat weights based on talent/gear?

Would it be possible for gem calculated DPS to account for socket bonuses?

Its kind of hard to see which gem is in which colored slot.

When I use a saved version of a character it doesn't save the buffs. So everytime I go in or switch specs/gear/etc.. I have to manually turn Dranei presence off. COuld saved version of characters also remember current buff settings? Also, if we could save different buff settings(for 10 man and 25 man as example) that would be helpful.

When I load my character it will have Swordguard Embroidery but the simulator won't let me choose that when I change cloak. I'm also curious about if it works in the simulator.

"Physical Miss" rolls up both misses and dodges. So you would need to be both hit and expertise capped for it to display as zero. My goal was to "boil down" stats to the ultimately meaningful numbers on the UI, thus why you don't see total strength or agility, and why misses and dodges are combined, since they have an identical effect on your DPS. That said, splitting miss and dodge on the UI may be a better choice to facilitate choosing gear.

But rest assured that your miss and dodge rates are being modeled accurately -- I just tested this quite a bit.

This is on the to-do list, but not implemented yet.

Unfortunately the armory does not provide sufficient data for socket bonuses. I can tell what socket bonuses you have active when you load your particular character, but I cannot determine the socket bonuses for random item XYZ from the armory. It's a strange omission on the armory's part. Thus, I just ignore socket bonuses entirely. It doesn't significantly impact DPS though, so coming up with some way to build up a database of socket bonuses is a pretty low priority.

I'll make sure to take the draenei aura out of the default "full buffs" for horde characters. A feature to save buff sets would be nice -- I'll put that on the future feature list.

Edit: looks like Yellow answered everything already.

It seems to be in the sim actually. I don´t get those weird results as before with Dual-Wielding being 200 dps ahead of 2H.

My sims are now more in line with the results of Kahorie´s simulator. But with my gear Kahorie´s Simulator values 2H > DW. With your simulator DW > 2H.

And i just want to know, how this could be.

Try actually running a sim with one over the other. Even if the DPS estimates are off, especially for things like trinkets and sigils, the simulations tend to be a lot more accurate.

*Edit- seems you're on to something though, Banner is showing a slight advantage over the Insignia on my DK as well, more noticeably with raid buffs (where the estimate shows Banner > Insignia) than in Self buffs (where the difference is far less pronounced, and sometimes sims a loss).

Perhaps there is a fault in the wonderfully fun and mathtastic stat that is ArP? I hear that stat is a delight to model.
