Death Knight (Forums / Talent Calculator / Skills/Talents)
Frost
Hungering Cold now has a 1.5-second cast time.

Glyphs
Glyph of Dark Succor has been redesigned. Rather than placing a 15% maximum health floor on Death Strike healing while in Frost or Unholy Presence, it causes the next Death Strike within 15 seconds after killing a foe that yields experience or Honor Points to heal for at least 20% of the death knight's maximum health..


This just was posted as the Official 4.2 PTR notes for 5/26


The glyph change is completely bogus - makes Death Strike completely useless now for Frost and Unholy. Frost survivability is already low.

I can't tell you how many times I'm won arena matches solely due surviving longer with Death Strike. Arrrgh.
