I just went back to Skyrim after about a year. Decided to start over rather than try and remember where my other characters are in the story. Downloaded the 3 DLCs before I started, thinking I'll get into those after I finish most of the main content. Big mistake. After I hit level 10, I started getting ambushed every 5 minutes by both groups of vampires and groups of "hired thugs." Kind of a pain in the ass.
