Except summoning undead minions is a major theme of the Death Knight. In fact it's one of its defining characteristics. Summoning elementals isn't really a defining characteristic of the Shaman class, and I would argue it isn't really a defining characteristic of the Mage class either outside of Frost Mages.
Foul Managerie turns some of your undead minions into exploding zombies, so yes that is waves of exploding minions.Army/Apoc are not waves of exploding minions. My spell is essentially a nuke with an extended animation. At no point are the skeletons involved in this spell of mine, pets. Bonestorm isn't a projectile - it's an AoE. Soul Reaper has nothing to do with ghosts (Do DKs have any spells that deal with ghosts?), and what is Dancing Rune Blade supposed to represent?
Bones swirling around the DK during Bonestorm are still projectiles.
Soul Reaper literally attacks the soul of your target and gives you a bonus if you kill them with it. Dancing Rune Weapon is a Ghost Blade. Wraithwalk turns you into a ghost and allows you to move faster.
Abominations spew disease as they attack. Death and Decay can apply festering wounds. Bursting Sores infects targets around the burst. How is that not a spray?Death and Decay, Defile, nor Abomination are diseases. Don't say diseases can do everything a poison can and then list non diseases. Busting Sores is not a spray, as in channeled function. DKs to my knowledge cannot deal damage in a channeled mechanic.
Then there are Death Knights, Necromancers who wear heavy armor.And yet, every Necromancer NPC in WoW IS a light-armored ranged spell caster.
No comment on the Shadowland Necromancer idea?
