Morokei was the easiest "boss" I've faced yet. I snuck into his chamber, found a spot to hide behind some rocks, and took him out with about 6 arrows. He never even found me....never could attack me.
I found the Draugr deathlord or whatever he was called, sitting on the throne near the shout word wall, to be much tougher. Of course, Morokei never even found me when I took him on. I'd shoot him with an arrow, let him search, then as soon as the "eye" closed and he couldn't find me, I'd shoot him again. Got the 3x bonus every shot.
