Hey guys. We ran more simulations.
For reference, my own Frost Death Knight, in 492 gear, has 6,700 Haste Rating, 4,165 Critical Strike Rating, and 1,100 Mastery Rating. Simulationcraft gives the following weights Str=2.94
, AP=1.12, Exp=2.08, Hit=1.90, Crit=1.14, Haste=1.22
, Mastery=0.91. I'm currently gemmed for Strength, and not Haste. So this clearly shows Strength to be "way" ahead.
I increased my stats to add more Strength at the expense of Haste (so, taking the example further), and I got Str=2.91
, AP=1.07, Exp=2.11, Hit=1.95, Crit=1.16, Haste=1.21
, Mastery=0.88. Hmm. Haste and Crit are closer in value here, and Strength still wins by a lot.
Now, if instead, I gem for Haste, and not Strength, I get Str=2.93
, AP=1.12, Expertise=2.07, Hit=1.91, Crit=1.17, Haste=1.21
, Mastery=0.92. Hardly any change, and Strength still wins!
I decided to look at someone with much better gear than me, and see if there were differences. I looked at the armory of Dmitrii, vodka's Frost Death Knight (http://us.battle.net...mitrii/advanced
). He is gemmed for Strength (although for some reason he is sporting a single pure haste gem in one of his sockets). His weights are Str=2.97
, AP=1.11, Expertise=2.10, Hit=1.93, Crit=1.39, Haste=1.79
, Mastery=1.00. Wow! Here, Haste is showing up as being vastly superior to Strength.
We ran a few other generic simulations, in several slightly different gear set-ups (but all with stats similar to what you'd expect to have if you are prioritising Haste as your secondary stat, and are discarding Mastery).
AP=1.10 Exp=2.45 Hit=2.21 Crit=1.24 Haste=1.58
Mastery=0.94 (this is with 9,000 Haste Rating, 4,000 Critical Strike Rating, and 2,000 Mastery Rating). > Haste wins (barely).
AP=0.99 Exp=2.25 Hit=2.09 Crit=1.15 Haste=1.34
Mastery=0.86 (this is with 6,250 Haste Rating, 3,000 Critical Strike Rating, and 2,000 Mastery Rating). > Strength wins (barely)
AP=1.11 Exp=2.53 Hit=2.24 Crit=1.19 Haste=1.69
Mastery=0.91 (this one is with a bit less usual stats, namely 9,000 Haste Rating, 2,000 Critical Strike Rating, and 4,000 Mastery Rating). > Haste wins (by a decent margin, but then you're unlikely to have this kind of stat distribution).
The list goes on, and there are variations like this all along - we tested this with regular amounts of Strength for the appropriate gear levels (15-19K Strength between pre-raid gear and Heroic gear).
Conclusion time? I don't know. Strength seems to be ahead, mostly. In some cases, Haste is ahead. In a few cases, they're almost equal. There isn't a pattern I can easily discern here, and the best thing I can say is to Sim your own character's weights and go with that.
Now, Ask Mr. Robot is using "fixed" weights for these stats. It's telling me to gear my character based on the same weights as Dmitrii. This, I believe, is a problem. I need to bring this up with the guys at Mr. Robot and see what they think.
So to bottom line all of it for you, I can tell you to import your character(s) in Simulationcraft and see what they say. Take that with a grain of salt; as I said above, they tell Dmitrii that he's "doing it wrong" and should be gemming for Haste instead of Strength, so either he's choosing to be wrong (it's possible), or he's not aware of Mr. Robot's suggestions (just as possible), or Mr. Robot is wrong with what it is suggesting (also possible).
I am sorry to keep saying "I will look more into it", but it doesn't seem like it's something with an easy fix or solution, mostly because I just don't know how much trust we can put in the results that Simulationcraft spits out (in this case, at least).
I'll keep you updated.
