I haven't really had any problems in Skyrim where I felt completely shut down in a fight. I'm lvl 30, have 1H, Destruction, and Light Armor all in the high 60s, high level enchants, and smithed all my armor to Legendary. I have the best set I could get at my point in the game too. Anyway, I started the Silenced Tongues quest in Volunruud, which is full of Draugr. I had no problems killing them until I got to a room where one particular Draugr Wight was one-shotting me with Unrelenting Force.
I reloaded and baiting the shout so I could get close during his cooldown and he killed me with two arrows, each doing over half my health. I actually thought this was the boss, but after cheesing him to death with Mjoll + Impact Lightning + Magicka potion spam, I discovered he wasn't the boss at all. Just some random-ass Draugr Wight. The actual boss was incredibly easy, but what the hell was with the Draugr Wight? A random "Screw You, Buddy" from Bethesda?
