You really don't want to start turning all your gems to ArP gems until you get over 1000 ArP from gear. ArP scales up alot more when you have alot of it. Once you hit the soft cap, keep your gems optimized for other things until you can get more ArP from gear. Getting Deathbringer's Will will help alot with this too. Post a link to your armory and we can maybe help you with some ideas for maximizing your dps, but if you're going the ArP route, you will only want to grab your 2-piece T10.

I am still confused. I've been getting some heroic ICC gear, and I'm in mostly 245s/264s now.. I've been gemming for AP because the spreadsheet has been messing up and telling me to gem fully for haste (which is a mutilation rogue thing..?). I went to talk to a druid about joining their guild, and she told me that gemming for AP is wrong and even if I was ArPen soft capped with the trinket, that soft cap sucks.. I only pull like 9.7k DPS on Saurfang..

I'm also having confusion about when to pop killing spree? I usually run into battle with ToT on the tank and Blade Flurry popped until i build up 5 combo points for SnD.. when i have 5 combo points, i pop killing spree, then when it's over i pop SnD then adrenaline rush.. then just do 5 point Eviscerate/SnD rotation until Killing Spree comes back up..

So, how do I fix the spreadsheet, and how do I open? I feel like I'm losing a lot of DPS with my current opener.

Haste is not neccessarily wrong, it's good for combat too. But try this, start putting ArP gems, see if you reach a cross over point where ArP jumps ahead. Because, the spreadsheet only shows you the current, so one gem may not be worth changing over to ArP, but 12 gems might push it over.

Get snd running before you do anything else. You autoattack during killing spree - for 20% more damage no less - so you never want to use it when snd is down. One point snd is all you need for its entire effect; it isn't evis where lower combo points mean a lesser effect. Sinister or garrote to open and press snd, every time. Then empty your energy bar, pop blade flurry and then killing spree right away. Refresh snd with as many combo points as you can build before the 1-pointer is going to fall off, and *now* you're ready to start your usual rotation.

Some people get 2 cps up to give them more breathing room before they snd, which only delays it by a gcd. I don't personally find it necessary, but you do you. Other people pop adrenaline rush immediately after ks is blown so that they can get a 5-point snd running on their first refresh. That is a compelling method because it also means adrenaline rush coincides with all of your ring/trinket/probably berserking procs. When you get the two-piece, don't have TotT already cast before you're hitting the mob because you're wasting that 15 energy. Just pop it after your garrote/snd opener when you're not at risk of energy capping.

Please fix some of those gems. Put a 10 exp/hit gem in your belt, shoulders and helm. You'll end up 2 expertise over cap instead of 12 and activate two additional (valuable) socket bonuses while you're at it. Right now you're trading 20 ap and 10 crit for the 12 agility and 30 hit that you could have. Notice that that's an entire extra gem's worth of stats.

Edit: The spreadsheet is suggesting haste because you have such an extraordinary amount of hit. Hit only affects white damage and poisons (directly), which is also true of haste. Your white/poison dps is so inflated relative to a typical rogue spread that the spreadsheet is simply trying to add the greatest benefit to your largest chunk of damage - but it is still correct in doing so. You'll see it stop suggesting haste when you lose a couple hundred hit points.

Ok, so the deal here is that you keep auto-attacking during KS, for 20% bonus damage no less. So your higher KS hits are being offset slightly by lower dps from Quel Delar. Do not forget to apply poisons to your off (bag) weapons as well, as both the KS and the auto hits can proc them. On top of both of those points, your OH hits as combat proc energy, switching to a lower speed weapon gives you less procs, and thereby less dps later (unless you are energy capping during KS).

Now for fan of knives, there are entirely different considerations. FoK gets a lot of its damage from the poisons on your weapons, since wound poison's proc chance is based on weapon speed, the slower weapons will have higher proc chances. I believe 100% chance on a 1.8 weapon. Take into account that all AoE is capped at 10 targets, but our application of poisons from FoK doesn't count as AoE, and you can net a nice amount of damage. The pulls on which this is useful are more far apart, and the method is usually not necessary, and very few boss fights can make use of this; LK being the only one I can think of. Combat during phase 1 can pop BF, target a ghoul and FoK to reflect all of the damage onto LK (was mentioned in ICC tips thread, I have never tried as I am mut). Mut can use the same idea to swap weapons and FOK to apply crippling to all of the valks upon them landing.

Wound is normalized around 1.4 speed weapons, so it has a 100% procrate on a 2.8 speed. But combat doesn't use wound poison, so it's unlikely you'll be hitting 100% procrate regardless. Neither mut nor combat achieves a 100% procrate with instant, even factoring in envenom and talents.

Aoe is not capped at 10 targets. There is an aoe cap for every aoe spell in the game, but that is a cap on how much *damage* it does per "wave." So as you get better gear, you will not hit the onyxian whelps harder and harder (apart from the exceptions below).

However, crits do not count against the cap. So If the cap were arbitrarily 40000 damage and half of your hits crit, you could actually exceed the "cap" and do 60,000. As Zulkeir said, poisons are not a part of the cap. If you really want to weapon swap for FoK, put a 1.8 dagger with berserking, instant poison and the highest dps possible into your offhand. It will hit harder than quel'delar.

The dps loss of weapon swapping (your swing timer resets) will outweigh any benefit you could get from using a slow weapon for those 5 extra hits. Don't forget that you don't have to swap once per ks but twice.

My ArPen question has been getting overlooked.. I've been searching around EJ and google to see how much the arpen soft cap is worth.. I can find stuff from bc for rogues, but everything else I've found is pretty much warriors and kitties.. So my question: how valueable is being ArPen soft capped with Needle Encrusted Scorpion? It seems like the horrible uptime of the trinket would make it not-so-good.

The soft cap is not good. It's not good because it's not the hard cap. That doesn't make it worthless, but your "how valuable is the softcap" doesn't really mean anything. Just know that you want to ditch the soft cap as soon as you can, so aim for as many arpen pieces as possible. Trust the spreadsheet to know when you can drop the softcap, and be sure to try gemming almost entirely arpen when you are testing this on the sheet.

Until you breach a certain point, soft capping with NES will still be better dps than dropping it. But you want to pass that point as soon as you can. Your question was probably being overlooked because it doesn't really make sense in the framework of these forums.

I played muti all wotlk but now specced combat cause i wanted to give a try and this way i can solo mount bosses etc. nvm

as of a single target encounter why is stacking Ks with Bladefury is to be recomended? i dont see the benefit in... and as we get close to energy caping in ks i dont see how extra combat potency energy through bf is at any gain.

Please enlighten me with your wisdom. Or did i miss something where bf+ks is not recomended an single targets ?

If I'm remembering correctly, KS increases damage during the duration of the attack by whatever percent, and stacking gives a small gain from applying that increased damage % to the extra haste from BF.

Armor reduction from armor pen and the armor reduced by sunder/faerie are independent. 100% armor pen does not remove 100% of a mob's armor, it just reduces the armor you can affect by 100%.

The answer to your second question is no. Sunder is too much of a dps increase to be dropped in exchange for some extra eviscerates/ruptures. Keep in mind that you will also never be the only person doing physical dps because all tanks do predominantly physical damage apart from paladins. In the unlikely situation that you are in a raid full of casters and only have 1 tank, who is a paladin, it will still be a dps increase to expose.
