I have been popping AMS just 1-2 seconds before the boss finish casting Blistering Cold in heroic 25 for the past few weeks and it works perfectly fine for me. I have never ever dropped below 20% or even 70% actually. There are a few reasons as to why you may drop so low with AMS. It could be that you are too slow in popping your AMS(server lag), or you are too early in popping it(there are random ticks that can easily consume the damage absorbed) and lastly your AMS is being consumed by Chilled to the Bones instead of Blistering Cold.

Assuming you are sub-frost, if you gain +hit from gems, you are giving up 20 haste to gain 15 str. Using i264 values, 15 str is worth (15x3.11) 46.65 AP, whereas 20 haste is worth (20x2.75) 55 AP.

Thus, if you need the hit, Precision is better than gemming.

Correct, but don't forget that if the person is close to the hit cap that they need to calculate the value of hit past what they need. If they are only .30% or less below, it would be better to gem for 10 str/10 hit in that situation (it's come up for me in the past).

It's only a small amount, but that's what we are here for

So speaking of Sindragosa I'm running into what I consider a problem with overcapping runic power. For our first heroic twenty five kill we ran with, I believe, four resto druids all with revitalize. World of Logs - Real Time Raid Analysis there is the log to how much I actually gained. Now my question is this; is there anyway to dump all runic power without completely foregoing a blood strike or letting a disease fall off at the last second?

Recently I have been noticing a few problems while DPSing with an Unholy sub-Frost.

On nearly all fights where movement isnt an issue, I get nearly threat capped by about the 1 minute mark. I usually only have 1 rogue TotTing me, and have two or three Paladins Hand of Salving me nearly on cooldown but I just catch right back up after the effect ends.

Am I doing something wrong, or is this normal? Or are my guild's tanks just bad?

I have never had this problem until ICC, but at the same time, I have almost always had Subversion in any spec I have used. I don't pre-pot, and usually wait about 10 seconds into the fight to start my rotation, but as soon as all of my procs go off it feels like I'm in Frost Presence(which I am not, I have been spamming a macro to shift into Blood Presence to make sure of it).

Any input or advice would be greatly appreciated.

TotT can swing threat pretty quickly, but with a 10 second head start it should be easily manageable. Your tanks might just be bad. Can't say for sure without more info or a WoL link.

If the rogue is ToTTing you on cooldown then thats the source of your threat problems... our DKS are always right below the tanks on almost every fight (and it isnt an issue with them, they are all very good tanks) and we don't get the benefit of having Tricks throw our way.

Make the rogue TotT someone else? :S

Well, I remember back when the patch was on the PTR I was talking about a 1/17/53 build with the other DK in my guild taking the point from Dirge... justification there being that we have plenty of incoming RP from Druids.

I guess I should've asked this before, but what are your guild's tanks?

atm, we have 2 Paladins, a Druid, and a Warrior rotating depending on the day.

If the Warrior is there, his Vigilance on me usually keeps me under him enough to not cause issues, but with the other tanks threat issues almost always arise regardless of which one is tanking.

For the past 3-4 weeks this has been occuring, I'm thinking maybe the ICC buff is causing it, since maybe our threat output with the damage boost is outscaling tanks threat output, but if i recall, most of a tanks threat nowadays is from damage isn't it?

This has to either be a bad tank problem or you run with 0 hunters. Get your hunters to MD and then the rogue to TotT the tank at the start then switch to you.

Also, I find it odd you guys are having threat problems or find yourselves so high on threat meters. According to WoL I put out pretty good DPS which means my TPS should be incredibly high yet I never find myself near the tank and in fact Warlocks, fury warriors, ret paladins and even mages end up being higher than me on threat in most fights (with me beating them in DPS). I only get in trouble on trash doing AoE since our tanks are pretty lazy about AoE threat so that's the only time I notice I do not have Subversion.
