Then again, my Level 19 Trooper completed The Esseles solo, with only Aric Jorgan as backup.

Check my thread, Legacy System Ideas, in the Suggestion Box forum. If those actually are put in to production, then the Legacy family tree would actually mean something.

Glad my ideas are getting some feedback.

My first idea is that NPCs will sometimes bring up another member of your Legacy who spoke to them before. An example is: "Stranger! Over here! I need help. Wait, I think your brother/sister helped me out once. Can you thank him/her for me? Anyway..." My second idea is that on certain Flashpoints, if you are groupless, you can be able to have another member of your Legacy within five levels of you with you as an extra Companion or assistant NPC. They won't be able make choices or gain Social Points or Experiance, but it would be cool to have them along for the ride, don't you agree?
