It was down for a second - the instance restarted for some reason. It is back up now. We're going to look at putting up two instances of the site to keep this from happening. For the time being, it will never be down for more than a minute or two. It is possible some small bug caused it to restart - we're trying to figure it out.

I see why it optimizes to "lower" stats in this case. For any class without a run speed talent, we are considering lavawalker and assassin's step as optimal. So, you go from 50 haste to 35 mastery on your boots. Based on your stat weights, it swaps out the int/mastery gems for int/haste, so you end up with a total of -10 haste rating, -5 mastery rating... but you run faster!

Looks pretty cool. I found the weightings to be pretty fair for my Arms Warrior.

The only addition I would LOVE to see is an option for PvP optimizing, or at least an option to change the hit/exp caps.

Thanks for all the hard work!

Ah ok, I see. You might want to make enforcing that an option, though.

Ah, the infinity symble in the cap column for spirit was kinda misleading

The tool suggests that reforging past the hit cap is optimal for my set of gear and stat weights:

Mr. Robot - Character Profile - World of Warcraft

The 50 mastery -> 50 spirit reforge on the neck would put me at 1763 rating, which is 21 points above the cap.

Your elemental weights are completely wrong, as is the meta selection.

Is there any option to disable it from reforging a certain item? If there is, I couldn't find it.
Anyhow, the reason I'm asking it since it's reforging Signet of High Arcanist Savor which currently is not reforgeable as the stats don't show up in-game.

I was testing on my low geared blood DK and when optimized it shows that I should use 5 JC gems while maximum allowed is 3.

LucidityAxel: I checked it and our tool comes out to 16.85% spell hit for him, just UNDER the cap, not over. Just to be sure, I double checked, and we are indeed calculating spell hit accurately

MatsT: I am not surprised that you are able to find an example where the optimization is very slightly worse. Like I mentioned in the OP, we are forced to use an approximate method in order to make the site usable. It is definitely possible for people to come up with slightly more optimal tweaks manually. This particular example is a little larger margin of error than I would like, though. We will see if there is any way to improve the algorithm. Thanks for the info!

Gir: There is no such option, you are correct. If that particular item is bugged in the game, we might be able to hard-code in an exception until they fix it.

Ayrea: Thanks for the link. We will fix that in our update today. FYI, I'm trying to check this thread regularly, but if you post technical bugs like this on our technical support forum (Technical Support) there are multiple people who read that board so we can respond to stuff faster.

Binkenstein: First off, we are aware that the chaotic meta is giving a slight DPS increase, even in it's current "broken" state. We decided to not take the time to implement these meta gems until 4.0.6, since it takes significant effort to implement each meta requirement in the optimization algorithm. Second, I will explain to you where our Elemental stat weights come from, since a lot of research went into them.
There is an Elemental BiS thread here: [Elemental] BiS gear and set-up discussion (4.0 and onward)

The folks in this thread have cleverly tweaked Elemental gear. Where possible, the method I use to create stat weights is taking known BiS gear sets and working backwards. One of the first things I noticed was that the stat weights SimC creates do NOT get us to the Bis setup. Here is a near-optimal set based on the SimC stat weights:
Mr. Robot - Elemental Shaman - World of Warcraft
This simulates out to about 3.74% lower than the BiS gear setup.

Using your stat weights from http://totemspot.com/2011/01/catacly...-guide-4-0-3/:
Mr. Robot - Elemental Shaman - World of Warcraft
This simulates out to about 9.34% lower than the BiS gear setup. Now, it looks like there is a problem with an interaction between these particular stat weights and the estimates we use for the Elemental set bonuses - we generally estimate set bonuses as a DPS increase, so we use the Spell Power weight to assess if they are worth getting. I modified your stat weights very slightly by bumping up spell power to get a more "fair" assessment of them:
Mr. Robot - Elemental Shaman - World of Warcraft
This simulated out to about 4.34% lower than the BiS gear setup.

So, I looked at the BiS Elemental setup and said to myself... why aren't these stat weights leading our optimization algorithm to the BiS setup? Using SimC's stat weights or totemspot's stat weights, the BiS set does not have the highest EP value. This means that the stat weights are not right. I tweaked the stat weights to create gear sets that are more optimal. Using the default stat weights on Mr. Robot's site, you end up with this:
Mr. Robot - Elemental Shaman - World of Warcraft
This simulated out to 1.66% less than the BiS setup. A portion of this can be attributed to the meta gem, which we are willing to accept until 4.0.6 patch. So, this achieves our goal of being within 1.5% of the optimal gear setup with our approximate optimization algorithm. Actually, I did find some stat weights that put me even closer to the BiS t11 heroic set, but then some weird stuff started happening at the t11 and pre-raid level. These weights still get good sets at all gear levels, although sometimes you can end up slightly under the hit cap. People can manually tweak the weights if being slightly under the hit cap with certain gear combinations bothers them.

So, TLDR: I think Mr. Robot's stat weights are more accurate than SimC's stat weights or totemspot's stat weights. We arrived at these stat weights empirically based on what the BiS elemental gear has been observed to be.

Toastmonger - We will add those enchants into the list.
