DW Frost prioritizes Howling Blast over Obliterate. But, Obliterate is still used to consume Unholy Rune(s). DW Frost loves Mastery, but it also needs a certain level of Haste to fill the empty GCDs. So until you reach Heroic T14 levels, then you need to prioritize Haste slightly over Mastery. As you naturally gain more Haste, the value of Mastery rises.
People are still trying to relate Cata terms with MoP and it can make things confusing. Nevertheless, DW Frost prioritizing Obliterate is no longer competitive gameplay.
