Epic SpellsFollow

Hey, I was thinking today while playing WoW. And I was thinking that all classes should get epic spells. Like from new spellbooks called something wierd. Like tomes and stuff. But you have to do a series of quests and then you get to choose one of the rewards. The rewards will be 3 incredibly powerful spells/abilities, and there would be one from each talent spec to choose from.That would be awesome, in my opinion.

What do you guys think? What "Epic Spells' should there be for mages?
