Actually, even in a raid environment with buffs the Infuser seems to fluctuate between about 16% and 19%. Here are a couple of logs from different fights in different raid compositions. The problem being ... even with added haste and crit, you still have to contend with "chance on crit". And if the chance on crit is only 10% ( my understanding ) ... then you are realling only buffing that 10% chance and there is no way it will bring your average proc down from 62.314 ( average from my dummy test above ) to 51 seconds or close .

This might have been answered before but i could not find a answer with the search function. Has there been any theorycrafting on Killing Spree weapon swapping? There is the option of swapping to slow offhand before using KS, just after using KS or not at all. I started using a KS macro that equips a slow (2.7) offhand instead of my fast dagger (1.4) and KS damage went up significantly, tho i usually lose my deadly poison stack as my 2nd offhand will have wound poison on. Also it is a bit tricky to find out how much damage got lost to the reset of the swing timer. Would be also interesting to know if the weapon swap resets swing timers for both hands or only the affected one.

All proc-based/internal-cooldown based math aside, you may be able to look at Mark as an upgrade simply because you get to choose when it procs (after two minutes, of course) as opposed to it proccing on its own. Regardless of whether or not you need the hit rating, things proc'ing in tandem can give you a dps boost that may outshine whatever slight differences the two pieces have in a non-situational, mathematical setting. It will clearly depend on the boss, how good you are about using cooldowns, and a slew of other factors; when I checked your armory, I saw you currently specced into and geared for mutilate, which would benefit less from the idea I just mentioned. Your combat spec, however, loves it when you stack cooldowns on top of each other, especially during Killing Spree. Since Killing Spree boosts all damage done by 20%, you can (simply put; the actual math is much more complicated) look at it as though all other cooldowns you pop during a killing spree are 20% more effective, as long as they aren't cooldowns that will serve no purpose during a Killing Spree (Adrenaline Rush). I apologize that most of this theory regards the combat spec; I have limited familiarity with mutilate at this point.

So from that standpoint, I guess my conclusive opinion is (like many things with theorycraft), "It depends."

If you just finished levelling him, why are you using lower rank poisons?

Re: Hodir hard mode
Does anybody know if singed is applied by rogue poisons?
We run our 10-mans with a very melee heavy group (not by choice), so I was just wondering how big a problem it is going to be.

edit:
Sorry, I just figured out how to find out the information myself from logs. Looked at who applied the singed debuff, compared poison damage between a hodir kill and an ignis kill.

For the record, rogue poisons don't apply the singe debuff, but it looks like poisons benefit from it.

That's the reason Mutilate will usually perform better than Combat on Hodir

I'm actually curious about this now after reading the question. It seems that a quick weapon swap would be a boost in dps during the killing spree, even more so if the swapped weapon had wound on it rather than deadly.

I do know that the problem with dropping deadly poison could be easily avoided if you ensure your deadly stack had a fair amount of time remaining on it. Obviously if you have 2 sec left on a stack, and then weapon swap --> KS, you're going to lose your stack.

Reading this post reminded me of the upcoming posibilities with weapon swaps for increased poison dmg, yet only doing it during a KS would seem like a fairly easy way to increase dmg.

Just going off my common sense and assumptions here, but I think the swap would outweigh any sort of dmg loss by the swing reset. I dont know however if it affects both weapon hands, or just the hand that was swapped.

Trash isn't about optimizing dps, it's about keeping people alive. Constant ressing and rebuffing wastes time.
Compare these 3 scenarios:

a) You use ToTT, SS, SnD, FoK. By the time you get to FoK your ToTT has almost run out.
b) You use SS, SnD, ToTT, FoK. Even worse than above, 3 gcd before you redirect AoE threat.
c) You use ToTT, FoK, FoK, (then SS+SnD if you want). Safest option. And probably even higher total raiddamage since every other dps can AoE instantly.

In my book, c) is far superior to the others.

You bring up a very valid point that I meant to include in my previous post. The ability to TIME the USE of Mark is proving to be a difference maker for me. I actually do raid combat ( my Mut spec is only pvp ) and dropping the mark on cue with all my other cds ... or at the same time as heroism ... or when XT's heart drops - is huge. I was actually really hopping not to like the Mark better than Infuser since I prefer not to need an extra button on my bar ... but all my practical use so far has in fact pointed to the Mark as a viable upgrade. It's still early though and I've not had a chance to try it in TOC raids ... but I'll be trying it tonight.

I picked up the 196 dps Gutgore Ripper today. Though it doesn't have any stats, I was wondering if the pure dps increase paired with the proc would outweigh the stats that [Twilight Mist] gives. I am running 51/13/7, The World of Warcraft Armory is my armory.

Thanks!

Historically, procs have sucked relative to stats. We will of course need to test the dagger (and the sword, and the axe) to see what the proc rate, but the proc rate will need to be extremely high for it to be competitive with stated item of the same tier.

In terms of comparisons to an item several tiers below: it's *probably* better, but when you consider the PvP weapons and how they stack up to their PvE counterparts, that's by no means a given either.

In short: we need proc rate testing before we can realistically comment on how good they're going to be.
