I'm going to go out on a limb here and assume you've not read the tooltip for Deadly Brew since September. It has no place in PvE.

You can find EP values on the first page of this thread. This should help you greatly when choosing gems.

So what you're saying is that you would rather drop say, 2 points in Murder, losing 4% damage to around 2/3 of the WoW mob types so that you don't have to wait (pool energy) a calculated 2-3 seconds at most to mutilate again?

Leto simply said he doesn't run the optimal setup because the difference in DPS in negligible when spreadsheeted (personal preference within the margin of error). What you suggest though is far from negligible no matter where you take those two points from.

The idea to Shiv to proc or maintain a DP stack isn't new but when talented that far into Assassiantion the down-time for DP should be very, very low. I would imagine the energy spent isn't worth the very slight increase in uptime. It's simply easier to pool energy until DP is up before Mutilating.

You are misunderstanding everything I said. I clearly put in my above post that Deadly Brew is NOT included in the build which is why I was saying not to put Instant in the OH. I understand the difference is small when not having deadly in the OH I was just saying the risk to me wasn't worth having deadly drop by some chance. But while I do understand that the downtime on Deadly should be low it is still a risk none of the less if you are trying to max your dps output.

But on the other hand if the downtime is low, or possibly never depending on gear, then I am sure his method will prove better.

Just a little support, if you're attacking the target, and deadly drops, you can expect it to be back up in at most 3 or 4 seconds, more often than not much quicker than that.

With reaction time and global cool downs, you probably won't notice and shiv until after 2 or 3 seconds anyway, so you're basically shiving to add 1 more second of deadly up time at best at the expense of a global cool down and ~37 energy. That doesn't seem worth it to me, especially with the extra amount of attention I'd have to pay to it if I was worrying about using shiv.

What are the different spreadsheets that are in development at the moment? I mean which ones can we really rely on for accurate information?

I can agree with you on the gear part some what. I've geared up quite nicely this past week and recently spec'd combat fist seeing as how there are not many great swords in the game currently (thaddius sword and the ebon hold revered one, none of both are above 150 dps) and my dps has increased quite a bit for now. So for now I'm aiming on getting the fist off KT which should last me until arena weapons are out.

*edit* actually, i just noticed the deadly swords are only 156 DPS compared to the KT fist thats 171 dps, fist spec going to be the best spec for a while possibly?

Wound Poison VII Damage (per attack)= .5*(231+.04*AP)=115.5+.02*AP
0/5 Improved Poisons Instant Poison IX Damage(per attack)= .2*(300+.1*AP)=60+.02*AP
1/5 IP Instant Poison IX Damage= .22*(300+.1*AP)=66+.022*AP
2/5 IP Instant Poison IX Damage= .24*(300+.1*AP)=72+.024*AP
3/5 IP Instant Poison IX Damage= .26*(300+.1*AP)=78+.026*AP
4/5 IP Instant Poison IX Damage= .28*(300+.1*AP)=84+.028*AP
5/5 IP Instant Poison IX Damage= .30*(300+.1*AP)=90+.03*AP

Setting one of the Instant Poison VIII expressions equal to the Wound Poison VII expressions and solving the resulting equation for AP gives the attack power needed for Instant Poison VIII to give equal poison damage per attack to Wound Poison VII. Any attack power above this value favors Instant Poison VIII, except where noted, and any value below this value favors Wound Poison.

0/5 Improved Poisons: No attack power will ever make Instant Poison VIII equal or exceed Wound Poison VII at any gear level; Wound Poison VII is always better without any points in Improved Poisons.
1/5 Improved Poisons: 24750 AP
2/5 Improved Poisons: 10875 AP
3/5 Improved Poisons: 6250 AP
4/5 Improved Poisons: ~3938 AP
5/5 Improved Poisons: 2550 AP

P.S. Something like this should probably be put into the TTT article. I'll post a link to this in the TTT article thread.

The formula is still the same as what Aldriana presented: you use a spreadsheet to figure out the DPS of having Icewalker versus the DPS of having Cat's Swiftness, then input those into the formula and figure out the breakpoint. In general, however, Cat's Swiftness's usefulness is currently reduced for three reasons:

1) Other upgraded enchants have increased benefits compared to their BC versions, unlike Cat's Swiftness.
2) Many raids may contain an Unholy Death Knight, who can provide Unholy Aura for the entire raid, rendering movement speed boosts unnecessary.
3) Many rogues are Mutilate, and have the opportunity to spec into Fleet Footed (which also might not be a worthwhile DPS tradeoff).

The Gear Spreadsheet is permanently discontinued, as far as I know, in favor of RogueCalc. The DPS Spreadsheet was put on hold by Dontmindme due to lack of time, as I recall, and I think he was going to be able to get back to it around December -- but don't quote me on that. The Roguecraft Spreadsheet currently has an unofficially-updated version available by sp00n, and I should be able to release the official update soon, hopefully.

So for now your option is basically Roguecraft or nothing.

I am quite new to handling EP values so could anyone clarify if the crit, exp, haste and arpen values are for rating or full percent?

What I don't understand is why it would make a difference which hand the faster dagger is in, just as long as it has IP on it. For that matter, wouldn't two fast daggers be ideal, what with the increased energy from focused attacks, and the greater opportunity to apply deadly poison?

Assuming similar DPS, yes two fast daggers is better than one fast, one slow.

The reason you want the faster one to be in the main hand is because you are going to place IP on the faster of your two weapons, and your MH slightly more IP proc opportunities due to finishers.
