So what is it? With combat and mutilate it seems to be AP but I see Taryssa with armor pen. I have even seen some rogues gem full hit and some T10 full haste. None match the dps output of a Mutilate AP rogue tho. So why the diversity in RA? or does it seem to even out no matter what you gem for to stack?

AP gemming as combat lol

To answer semi-seriously AP/Haste are the highest value stats for Mutilate at the T10+ gear level.

ArP is the highest valued stat as Combat for the same gear level.

Combat’s Haste and ArP values dance with each other a bit between tiers, but ArP ends up on top.

The only time my suggested gemming changes on a spreadsheet is when I reach 100% armor penetration.

Rogues should only gem hit when they are over the crit cap or under the poison hit cap.

Combat gems to hard cap ArP because when they get near the cap, the value of ArP is a lot higher than both AP and Haste. Some rogues stay with AP and Haste gems because they have their dual spec as mutilate and ArP is pretty much worthless for that.

Mutilate gems a combination of AP and Haste, each one directly affects the value of the other.  You’ll need a spreadsheet to see which is worth more with your current gear.

As you get near BIS gear, the gap between combat and mutilate is pretty small. Combat can pull ahead on fights where you can utilize blade flurry and its more useful during short burn phases. If you don’t have an arms warrior in the raid for 4% physical, a combat rogue will add a lot more raid dps than a mutilate rogue (if the 3% crit buff is covered).

You clever rogues ;)

Yeah, we’re kind of a big deal :D

Well I re-gemmed all my gear to armor pen from AP. On AP gems with just poisons I was able to keep a steady 4.7k dps on the dummy with no CD’s. With ArP its a steady 5.1k. Thanks guys

Sweet deal, no problem. Post whatever questions you’ve got for us here. I can also be reached in game for a live consultation but I may charge an hourly!

And just wait for a fully sundered faerie fire-d mob in a raid to bust out on like Saurfang, that 400 dps difference will probably turn into 1k+
