sacridshadow, you've complicated things abouth your model that it does not make sense. If we here are talking something about logic and reality, your idea of necromancer is not suitable, like you say there are no coralants for naga race, they would shatter, or that underwater arrows would be against gravity. It is unlogical to create a Naga Death Knight Necromancer, it is logical to replace that with the Naga Death Knight. Why? Because necromancer is a thing that only burning legion and undead have and few corrupted races, the naga are not on the side of undead, Death Knight is a class in WoW which all races can become, which means it is a interracial class, so the same is for naga, example trolls do not have any connection with the death, aren't corrupted and can become death knight, the necromancer has similar spells to death knight, WoW was planning to add a necromancer class but they did not release it.
