Idea: Resetting Story Progress
Basically, lets say you made some choices you didn't agree with (like, for example, siding with a faction on Iokath). This feature would allow you to start over from certain points in the story. For example, if you choose to start over at the beginning of the Fractured Alliance story, all your choices beyond that point will be wiped, though you will still keep any unlockables. I say this because in Onslaught, for Imperial Saboteurs the game doesn't tell you that the Light Side response to Krovos on targeting civilians also lets you keep your cover, so many pick the "Saboteur" option, which still leads to Krovos targeting civilian population centers, which causes Theron to be upset with you.
