Well hearthfire IMO is going to revamp magic somewhat. Hearthfire is a month, also it's a skill book in skyrim that teaches CONJURATION. So maybe necromancy will be a huge part in it. But I really wish that they bring back spellmaking. If Beth does this, that would be amazing.

They need magic revamp, desperately.

Isn't heartfire a blades reference? The books talk about "The Night of FIre" But that took place in Frostfall, not heartfire.
