I honestly think its more annoying for higher leveled characters, as on lower levels theydont fus ro dah you off your feet.
Oh, I'm talking about the mages themselves. Not the draugr they control. We're talking about Ansilvund, right?
The toughness is that it's dark and narrow, gets a little cramped, and the mages might cast Fireball or something equally damaging. While the draugr beat on you.
Funnily enough, it's a school like Restoration that makes it easier.
