Bounty Hunters, Troopers, Jedi Guardians, and Sith Juggernauts are the only classes and advanced classes in which Heavy Armor is the maximum level of armor proficiency. While these classes can wear light and medium armor (for aesthetics or otherwise), it is recommended that they should wear heavy armor to maximize their armor rating and, ultimately, their damage reduction.
