There seems to be some confusion regarding the Faction Boxes and exactly what parts are not tradable.
To clarify, the regular 15 boosters that come inside of the faction boxes are all tradable to players or in the Saga game market. The troops that you receive from opening regular boosters AND from the faction boosters are all tradable. The only items that are not tradable are the 5 faction specific boosters ONLY while they are unopened. These items have never been tradable in game and are meant to give players a jump start on collections for a specific faction
