You can't be serious lol. Counting those as ranged classified things.
Not only are those abilities belonging to a melee class, they also have shorter range than most other ranged class abilities.
Not to mention a necromancer would be purely ranged with staves and cloth clothing instead of heavy weaponry and metal armour.
Soul reaper is an ability. Not a specialization. DKs in fact do not specialize in soul magic.
Please spend more time understanding how Warcraft and its lore and world works before saying something should or shouldn't be.
Lemme just repeat this: You have no argument against necromancers other than "lul DK". Don't lie, you just don't like the idea because it's popular and often asked for. You're annoyed by it. But you'll remain silent when it's eventually put into the game.
