In every biome there are one or more mobs that you look at and go "Hmmm, maybe I shouldn't try to tank that with last biome's gear." Two-star Draugr are definitely in that category. These are things you need to either avoid, or make a plan for how to deal with them. You're not on the top of the food chain until you have maxed out the current biome's gear, and even then you can get overwhelmed if you're not careful. Any time you go into a new biome, go slow, sneak if you must, and run away if you need to.
