It all comes down to how good the procs are and how many fading lights you get.

I did the #22 parse on Ultra H25 with low haste (1400 give or take) and 2380 mastery. Had only 1 heroic SC with that kill though.

It is only 1st, maybe 2nd raid. Then you will dps with right priority and watch tv at the same time.
My fingers pressing right buttons without any brain activity.

Question:

If I go Frost normal spec/priority how much haste should I shoot for?

Reason I ask is, when I check WoL a lot of DK are going for 2100-2200 and stacking rest on Mastery.

Or should I be going full out haste? I can get around 2540 haste with 1200 Mastery, or 2150 haste with 1650 Mastery (ish)

What do you think I should go for if I stick with Hastefrost. Sims will always say haste but from WoL it looks otherwise.

If on a single target fight (Ultraxion) these DK's are hitting the highest possible DPS on Frost with said setup, it will prove better on AoE fights also so I don't see why stacking haste would be better.

Opinion?

Those numbers aren't deliberate targets. They're just the values you end up with in BiS gear.

Take someone like Ibanel @ Lightbringer - Game Guide - World of Warcraft as an example. He/she isn't shooting for those mastery/haste values, that's just what you end up at with exp/hit cap and a full haste reforge in that gear,

Sometimes stars aligns and sometimes not. There are always been situations where you are starved with resources. When I played in haste (now I playing full mastery/1750haste), I dynamically changing my "roration" to HB spam (more RP -> more FS -> more runes from RE) if I feeling starved and changing back to Obli when feeling that I became gcd-capped again. Generally there is almost masterfrost priority. In "classic" priority for hastefrost you just wait for recources and hit obli again even if it means that you will wait again.

For me there is no difference betwen masterfrost and hastefrost priority. All the difference is how many haste I have and how many procs of RE and Rime. More haste = more Obli, less HB and vice versa. Maybe that is not right.. but I am always got to wol tops with my priority.

Been following this guy/gal for quite a while now and i must say i am quite impressed with his logs/playstyle.

He seems to be playing masterfrost as well although his DPS seems to be abnormally high comparing to others. Might be wrong.

Judging from his logs he isn't playing the usual masterfrost priority or else his HB damage would be way higher. In fact, he plays a more Obliterate oriented playstyle, which over 85% are crits. His Frost Strike crit % is way lower, which suggests he uses Killing Machine mainly on Obliterate and uses Frost Strikes to proc runic empowerment as soon as a rune set goes on cd. Also, he is specced to Epidemic instead of Imp. Blood Tap, which makes it even harder, seeing his haste.

He seems to be having insanely good RNG with Freezing Fog and Killing Machine procs and I think that about explains it. Too bad you can't see runic empowerment procs on WOL, however he can only have awesome RNG on that as well.

For example on his Ultraxion 10 heroic rank he had 70% Freezing Fog proc rate per Obliterate and 17.5 Killing Machine procs per minute, while for example myself on the same fight with much higher haste (assuming his haste remained around the same of what his armory says) I had 45% Freezing Fog proc rate per Obliterate and 15 Killing Machine ppm.

So all in all, a godlike player with excellent gear and excellent RNG.

I must admit this player's parses are fantastic and most likely the player is also, however not as slam against the player but if you closely inspect his/her dps numbers through some of the parses you will see why the dps is higher. I believe some of the parses have been generated with the help of the strategy and make-up of the group. For instance on Heroic Morchok, he/she does not get out of the black goo which will increase dps(e). Furthermore there is no rogue in the group, so fights like Blackhorn and Zonozz will allow this player to cleave more with HB and get more damage output for the same amount of attacks.

In regards to whether the player is MF or HF. I'm assuming you are referring to the parse from 3/23 not 5/3. On the 3/23 parse, its a bit tricky however I would have to lean toward HF or a hybrid build that allows for more haste. I say this because I compared that parse to one of my own that had similar fight lengths and that player had more melee attacks go out that landed and missed.

All DKs do this. On 3-4 stacks use AMS and it absorbs next damage and prevent aplly new stacks. You finish with new 4 stacks (after AMS ends) and 50% hp. It is all without external heal. So, what reason to move away from goo?

I never said there was anything wrong with it. It was more of a comment about strategy and how that can change someone's dps. If you take a look at the sentence prior to your quotation along with the quoted sentence, you can see that it was in example of the situation.

By the way, not all DK's stand in the goo. Personally, I have a 102 parse on H Morchok from actually standing out, however I also have an unfortunate miss-logged parse that was at least 8% higher from standing in. Once again, an example of how strategy can increase your numbers.

If you're an orc, No'Kaled is the clear winner on pure single target hastefrost. If you aren't orc it's a bit closer, but in pure single target it's still the winner. The problem arises in masterfrost and AoE since while mastery does scale with 1/3 of the proc, it loses you a large chunk of strength which means that your howling blasts won't do as much. So you mostly you're going to have to base it on the fight.

For any fight without any major AoE, No'kaled is the clear winner (Morchok, Zon'ozz, Ultrax), but for fights where you'll be getting a huge boost in your dps from AoE or missing lots of melee swings due to movement (Zon'ozz, Hagara, Blackhorn, Madness) Souldrinker will be better due to stronger HBs. Spine is somewhat of a wash since SD's proc will help against the debuff a little bit and I'm not sure how their procs work (ICD / pure % ?) in relation to tendon DPS, but No'kaled's proc is very relevant if it were to proc on a tendon.

That's the long answer.

The simple answer is No'kaled.
