granted there is a bonus for having 3/5 and 4/5 Rakata Tionese or Columni gear. If you have 3 or 4 of any of those you get a bonus to certain stats depending on what class you are.
The bonuses are for Head Chest Legs Gloves and Feet if I'm not mistaken.
That is why they are always saying putting mods in Rakata shells.
Granted the Tionese gear is pretty hideous for a trooper and for a smuggler I hope you like capes.
