[Hotfix in testing] Frost Strike and Obliterate have been reduced to their pre-6.2 damage levels.
The change to Might of the Frozen Wastes remains in place and is a significant buff to Frost Strike damage while dual-wielding.
Obliterate once again deals full damage to players.
[Hotfix in testing] Howling Blast damage has been reduced by 13.5% but is still a slight buff from its pre-6.2 damage levels.
The change to Howling Blast's area damage remains in place, and continues to deal full damage to all enemies within range.
Edit: Looks like DW Frost single target and Unholy for aoe?
