I strongly suggest that Gorefiend’s Grasp should become a class wide utility option for all DK and be available in the Death Knight Tree.
Since I will assume that DK’s won’t get a Raid Buff or something very relevant for raiding, it is important to make DK dps specs relevant in some situations other than dmg and our singel target grip.
Here is my proposal what to change:
Since Gorefiend’s Grasp is currently in the Blood Tree where 20+ Points need to be used I will keep that the same here. I have also spotted that Will of Necropolis is in the same row as Gorefiend’s Grasp so it would be a perfect one for one change.
