Don't take this the wrong way but; the life side of death magic? Isn't that a cleric?
I look at that 2E Description and I see a writer desperately reaching to try and find a way to avoid saying "Necromancers raise the dead," because he's been told parents will read that and throw their kids books away.
Necromancers are dudes who raise the dead. If you want to be a leader who keeps people alive...that's a cleric.
Now, I can buy the idea of a Necromancer who isn't Evil, but *purely as a deliberate subversion* and even then I'd expect it to be a Faustian bargain. I agree with...whatever edition of D&D that just flat out said "Raising the dead is an evil act." Yeah. Seems that way to me. Certainly that's the association we make with the word Necromancer.
I haven't checked out the preview yet, but if Necromancers aren't dudes who raise a LOT of undead, even if only as minions (actually, probably IDEALLY as minions) then Ima be pissed.
