Agreed. Only these people are trained users. Those with points in just one of the two skills, and no perk, are novices in a lot of meaningful ways, however good their aim is. That's a major point of Martial Arts – i.e., that actually learning a comprehensive style that accounts for more than just "hitting stuff" has been the mark of all professional warriors, ever. It is frustrating at times that people think that since skills are available piecemeal, cherry-picking the ones you want is all it takes to be a warrior . . . and then grow frustrated when they realize that Rapier doesn't cover off-hand knives or parries with the mailed hand, or grappling with a sword, or punching with a hilt, etc. Meanwhile, there are perfectly good rapier styles that encompass Main-Gauche, Rapier, Wrestling, etc.
