Another good point I mention, is that "basics doesn't mean only doing the very beginner move right, the exact same way it was taught to you in the very beginning.
For instance, when throwing cuts in longsword, you don't have to follow the swing the whole half-way around your body, as you probably did in the beginning to get the edge alignment correct. You can immediately drop into guards, follow with a reverse cut with the false edge, ect. (I know those are incredibly simple things to do after a cut, but they are just for examples) You wouldn't be doing it the same way, and some might not call it a basic, but as long as you maintain the correct movement (in this instance a cut) you are still keeping your basics strong.
