The idea of being able to heal our mates by dealing damages is cool, but i don't think that it's a good idea for Death knights, well simply cause Death knights are known to heal undead creatures and not alive ones...
Or ... GLOBAL LICHEBORNE AURA
Do people even try and think these through anymore? How does one make the jump from death to healing?
Would prefer a caster dps like the original DK was.
The ONLY good thing about DK healers, would be that PlateInt gear gets an additional use..
Other than that, NOOO!!!!

Wasn't there already another DK Healer thread (which used the name Necrotic too) only a few hours ago? >.<
DK healer: No. DK healing doesn't make any mechanical or lore sense. Mechanically, using your own health for spells and gaining health is proved to be an imperfect idea (read: Warlocks no longer rely on Lifetap save rarely), and to have a healer rely on casting from health is silly. You need a good resource to heal and DKs don't have good healing resource (doesn't have to be mana, per se, TOR worked well with energy healing, but I think Blizz wants to balance healers via mana)
Lorewise, Death Knights have an unsateable urge to inflict pain and torment, healing would only make that worse. Also, there is the argument that Death Knight "magic" comes from their runeblade, so most if not all unholy spells they cast must be in some form physical, but I digress.
A sublime idea. Only one catch: the ideal would be an autonomous class with a specialization to heal with blood magic, in the way seen in the video. A different class of the Death Knights. I am obviously referring to the Necromancers.
For the Necromancers, a needed class!
