Would you like to see a Necromancer class kinda like this?
armor: cloth (or mail?)
Specs:
Death -> range DPS: direct powerful shadow spells, curses and temporary spectral summons.
Plague -> melee DPS: physical dots (bleeds, infections, curses), uses two daggers or scythe (new weapon anyone?)
Blood -> HEALER: blood shield, can transfuse self heal, buffs through insane vials. Mana pool is a secondary health pool
Short intro:
Like DKs, they will have its own starting area, with the boss Kel'Thuzad. You will be a tortured citizen that had to join KT service. Your quests will be brutal and merciless (like DK ones). At the end, you will have to flee and you will join Horde/Alliance without revealing that you're a necromancer. Your NPC faction will think you're just an homeless guy escaped from the scourge.
