So I am planning a new play-through as a mage and am unable to decide which school of conjuration I should specialize in. Should I be a necromancer or a conjurer who summons Daedra?

Also note that for the latter, I don't plan on using Dremora. They are a bit unfriendly to my RP and overall image of my character. I plan on sticking to seekers and atronachs should I decide to go that route.

I said summoning atronachs. Raising dead can be a pain in the ass sometimes.

Well, that depends on how your character is. I don't really know how the RP goes so I'm not sure which would fit better.

If you have Dawnguard however, don't forget that Necromancy allows you to summon Wrathmen and what not. Pretty badass fellows.
