it could be where if you had a character at level 50 it would unlock the third faction (which would start at level 50) similar to the death knights in WoW

yea it would be extremely hard for them to implement into the game but it would be cool and i still want them to make characters affected by their family other then just getting skills from them like similar to companion quests you could get legacy quests that relate to your family

What i mean by affecting conversations is that you will sometimes in conversation be given the choice to say something that has to do with your family an example would be, a sith warrior has a trooper child and in a conversation the trooper is having the npc he is talking to could say something that is a big insult to sith and then the trooper could respond telling him that his father was a sith and that he doesn't like him insulting his heritage or something like that if you have any comments on my idea or any way to improve it please feel free to do so

and by the way does anyone know when the legacy system is going to be added?

I am actually really excited and cant wait for the legacy system i think it will be fun to be a sith trooper who inherited from his father, an evil sith warrior , the ability to force-choke enemies, or a smuggler that is strong in the force . i am really looking forward to it and am so excited to be able to make a big family tree that connects all my character together
