My sentiments exactly. After so little screentime, it could seem as though the Knights of Ren amounted to nothing, thematically speaking. Looking at the movies, personally, it's hard to argue against that point. Looking at the comics, however, it could be seen as a point in time when Kylo Ren saw how other Force-wielders thought beyond the scope of the Jedi and Sith. Here, the Knights could function as the catalyst for Kylo Ren's mindset of carving a different path.
