I'm not sure where I was getting it from on my spreadsheet, but it was probably before I fully configured it to my spec and settings. Disregard my post, sorry.

Using Cold Blood with make both hands crit when you use mutilate, thats pretty much what I use it on since I get ~3.2k crit with each hand when in a raid (10 man).

My envenom crits sometimes creep into the 7k bracket but seems to depend which classes are present (ie what debuffs are on the mob and if they increase spell dmg taken)

The DPS difference is minimal considering Cold Blood's long cooldown. I'd encourage you to use it instead to maintain cycle stability - it guarantees an extra CP on mutilate, which is handy if ruthlessness fails to proc when you want it to - or to increase the burst threat of a ToT to your tank.

Personally, just for fun and to keep up with the hunters, I'll save Cold Blood and pair it with Fan of Knives on trash Won't leave a bruise and it'll let 'em know who's boss...there's NOOOO doubt about it

I might need to reconsider this since getting Sinister Revenge last night, but my envenoms can crit for upwards of 10k, and my mutilates hit extremely weakly, since I had been using Webbed Death MH with Librarian's Paper Cutter OH. With Sinister Revenge, that may change upward. I haven't really been having that much difficulty maintaining a cycle with or without ruthlesness procs, and since Mutilate has +15% chance to crit anyway (bringing it to >=~50% chance raidbuffed, or 75% chance for one of two hands to proc on the attack, granting me 3CP anyway), it might not be 'that' necessary.

Again though, that may well change once I get 4pc Bonescythe and/or lose my Slayer's bonus, as well as having fewer 'crits per second" with Sinister Revenge rather than the paper-cutter.

On another note, even with the 1.3 offhand and a 1.4 mainhand, I tended to find myself "poison-starved" occasionally when it came to envenom while using Deadly on my main-hand and instant on my offhand, at least for the purposes of Envenom. Might well be worth looking into further, but with Deadly on a 1.8 mainhand, I can anticipate those issues being worse yet.

Is there a reason you're using WD/SR instead of SR/WD? I thought latest version of the spreadsheet with the Mutilate offhand doubleproc logic showed using WD offhand with IP, SR mainhand with DP was the superior option.

Mostly because of what I stated earlier in the post- I view as the doubleproc offhand logic having been already accounted for in practice when "logic-checking" the spreadsheet, and am wary of deadly poison uptime with it on the mainhand.

I'll give SR mainhand a spin during tonight's raid with deadly though, just to compare.

Yeah, I hear you. My current thought, though, is that when we're talking about an 11DPS delta out of a nominal 4300, any "cycle unreliability" will hit harder than the theoretical DPS gain in swapping hands/poisons.

Sorry if that has been posted already, but the HaT spec of the first post advices taking Shadowstep (instead of 2/2 Blood Splatter).
Isn't Shadowstep considered being not viable? Maybe a more adequate spec would be something like this.

Regarding to hit-expertise issue i'd like to ask a simple question.

In WOTLK guides it says that expertise and hit are the same stats. So let's say i got X much of hit and Y expertise. Also it's been assumed that cap is 755.

So is it okay to say that i have X+Y amount of hit ?

Thanks in advance.

I believe it's kind of subjective. Shadowstep allows you to get back to the boss faster and that might be worth more to people.
Also some are finding straight Eviscerate spam yields more damage than Eviscerate + Rupture but there has been no extensive testing.
