3.2.2 Death Knight Frost Tank Rotation Discussion & Questions
Disclaimer: I've never played a frost tank. I've started researching them, and haven't found sufficient data on rotations. I have several questions, and so wanted to start a discussion here.
EDIT: I tanked for the first time last night in mana tombs with my 68 DK. Turns out HB has a cooldown I missed when considering the rotations below. So, disregard the ones with multiple HBs which wouldn't fit in the 8 sec cooldown :)
IT = Icy Touch
BS = Blood Strike
PS = Plague Strike
OB = Obliterate
Tap = Blood Tap
HB = Howling Blast
PT = Pestilence
BB = Boiling Blood
D&D = Death and Decay
1) Single Target Rotations
I've seen 2 main rotations discussed.
a) Single Disease
open with: IT > BS > OB > (Tap) OB
main loop: IT > BS > OB > OB
b) Full diseases
main loop part 1: IT > PS > OB > BS > BS
main loop part 2: OB > OB > OB
I am having trouble thinking of a single spec which would benefit from using the single disease rotation over the full disease rotation. They both have 4 obliterates per 2 rotations, but the full disease one will have each OB and BS do more damage. Further, I would be suprised if any spec was able to make IT > PS if frost fever were already applied but blood plague wasn't.
Am I missing something?
2) Multi target rotations
I've seen several.
a-c have no glyph of disease.
a) HB glyphed single disease
Open with: D&D > HB > BB
main loop: HB > HB > BB > BB
Not sure whether alternating that with HB > HB > HB would be better or worse.
b) No HB glyphed, single disease
Open with: D&D > IT > PT > BB
main loop 1: HB > HB > IT > BB)
main loop 2: HB > HB > IT > PT
c) No HB glyphed, full diseases
Open with: D&D > IT > PS > PT
main loop 1: IT > PS > PT > BB > HB
main loop 2: HB > HB > HB
d) Glyph of Disease, full diseases, no HB glyphed
Open with: D&D > IT > PS > PT
main loop: HB > HB > PT > BB
From what I've read, it seems the theorycrafters don't like having HB glyphed. It is pretty useless in single target fights, right? Or can you ignore IT after your opener and just rely on HB for diseases?
GoD I also don't see very often in recommended glyphs. (Presumably because some other glyph grants more TPS, but has anyone really analyzed the different rotations?)
So, what is a good multi target rotation? Again, if you look at b and c, you get the same number of HBs every 2 rotations. Wouldn't having blood plague on all targets be better than just getting in an icy touch since the target will already have frost fever applied?
Also, when to switch from single target to multi target? I.e., I assume you wouldn't want to use multi-target on 2 mobs? Are rime procs of HB sufficient to hold aggro on 2 or 3 mobs? If so, why wouldn't they be sufficient on any number of targets?
What about hybrid rotations? I.e., if facing 2-3 or 2-4 mobs, open with rotation c above, then switch to the single target rotation? The D&D would generate good AoE threat...
Any theorycrafters who have analyzed the best rotations for TPS, and when to switch? (I.e., best TPS rotation vs 2 mobs? 3? 4? 5+?)
Any speccing considerations in what rotation to use? Or is it just dependent upon which glyphs you are using?
