I know Necromancy is what most people would chose but I always like Atromancy, the only issue is I don't know what they added and if going Necro would be better? I know they added some spells but I don't know what.

All the new conjuration spells summon different kinds of skeletons if I recall correctly.

So that will be necromancy right?

I believe so, I'm not a big magic guy myself.
