Masterfrost is a rotation priority that DW Frost uses when choosing to follow a Mastery > all stat priority. (but Sinzaram's post suggests it's actually the same priority for DW stacking Haste... D:)
Hastefrost is a stat priority that favors Haste > all.
2H Frost is always Hastefrost and so the 2H Frost rotation priority can also be considered Hastefrost.
DW Hastefrost is thus a DW Frost DK that follows a Haste stat priority and imitates the 2H Frost rotation priority.
The difference between 2H and DW Hastefrost is strictly which ability has priority when spending Killing Machine, or faced with resource capping (FS vs. Oblit).
Is that roughly correct?
I was actually just trying to sort out the different questions the OP seemed to be asking, because I find the topic interesting and I'm trying to learn Frost DK myself right now. Again, the terminology is really ambiguous at first.Your #1 is not competitive performance, you want to gear for mastery as DW. Your #2 is really not competitive-- are you really asking if it's OK to prioritize obliterate as DW? The answer is no.
But both of my questions resulted from statements made in the EJ guide which seems to play down the difference between Masterfrost and "2H-esque" cycles for DW. I find this interesting because everywhere else the sentiment seems to be that using the current 2H style as DW is a crime against nature.
I'm still trying to understand the EJ guide's assertion, which again strikes me as strange in the context of everything else I'm being told:
So is that describing what you're referring to as "DW Hastefrost"? If so, does that mean the 1-2% listed loss there is actually closer to 6.2%, based on the numbers you posted?It is entirely possible to dual wield and not use the “masterfrost” priority and instead use a more 2H-esque priority by using most of your runes for Obliterate rather than Howling Blast. This is a slight DPS loss (between 1-2%) and favors more haste over mastery (Strength > Hit/Exp > Haste > Mastery > Crit).
