Favorite type? That would have to be Vampire inhabited dungeons, closely followed up by human inhabited dungeons (Bandits, Marauders, etc.) Not only do these types of dungeons give good loot, but my character has a dislike for Vampires, Bandits, and Marauders, as they harm the citizens of Cyrodiil. My marksman based character has extra fun in these types of dungeons, as a single, poisoned arrow can put down most enemies. They never even knew I was there.
Least favorite type? Without a doubt, Goblins. I despise these wretched beasts. I believe them to eat humans, as I find a lot of human skulls in their caves. However, it is always fun to steal the Tribal Totems, as I can place them anywhere I'd like when I'm bored, and watch a Goblin war.
