Reaver is not a DK even though he used good amount of dots that do death damage he is still a tank. Void Knight is VK anti caster but he is more master of the arcane that the actual death knight.
Can we have a melee version of a Necromancer for the new soul. Imagine Death Knight with Undead pets (solely DPS Spec).
Please Riot make death knights in the game because they are awesome
