100% sure half that time is idling. no fucking way 12k hours.
This game was released 2010, it's 2013. Say you play 5 hours a day for every day of the year. That's 1800 hours for each year, so about 5400 hours can be maximum expected of actual game time by now. So yeah, keeping Warband open is the result.
