In JFO, we had the opportunity to create a new class of elite troopers that would assist the Inquisitor in hunting remaining Jedis and force users. You can think of them as a special force unit. They would be specially trained and would specialize in one of four types of weapons. This opened up a lot of gameplay possibilities and variety.
On a visual note, I wanted them to feel imposing and foreboding. We bulked up the silhouette by adding a shoulder pauldron and a kama (Star Wars language for trooper skirts), making their armor black with the occasional red color pop, white/silver graphic logos and a faint redish glow in the visor.
