I've made a number of significant improvements to the spreadsheet and a new version is available for download.
-Redid armor/armor penetration calculations for 3.1 according to the math done by the posters on the Combat Ratings thread and in particular Rallik's armor penetration formula found here:
http://elitistjerks.com/f31/t29453-c...6/#post1170842
The armor calculations are no longer using Vulajin's original tables in DPSCalc2. I created a new sheet named ArmPen that has all the work. There's a bug on the PTR the reduces armor penetration effects (Mace spec/arpen rating, not sunder/expose) by 19% (dividing by 1.25) I included the option to ignore or enable this in ArmPen.B1.
One thing I'm not quite sure about is at which point of the calculation Serrated Blades comes in, as the last remaining ability that reduces armor by a set amount. I'm going to do some tests on the PTR and figure it out. Currently I assumed that the 640 armor pen from SB is subtracted from boss armor first, before percentage effects, and not last. Being subtracted first means SB is weaker, and vice versa.
-Changed Mutilate energy gain to account for less HfB cost over time in Cycles.B1, Cycles1.B1, Cycles2.B1. About a 150 dps increase for Mutilate specs.
-Implemented Ulduar trinkets Wrathstone and Pyrite Infuser.
-Fixed a couple of minor item errors. While I'm on the subject, I included all the new items from ptr.wowhead.com. I've been made aware that there's other rogue loot that hasn't been uploaded to Wowhead, however, I'm not going to include it at this point.
If you encounter minor errors please PM me. Thanks for the criticisms so far.
