I understand.All TV shows with any sort of action sequences utilize stunt doubles, because you can't afford to have your main actors get hurt. If a stunt guy ends up in the hospital, that's unfortunate, but the show can go on. You need your lead actors to be on set the next day, and to shoot the next episode in the next week. Obviously, you want actors who can do their own stunts (to a point), but there is certainly not going to be a goal to produce something with battle scenes without the use of stunt doubles. It's up to costuming and directors and coordinating between the actor and the stunt double to make the transition seamless and invisible.
