I know this has been/is being discussed to death in the EotE Forum but the last word from Sam was a little vague for some and there is still ongoing discussion.

If you're not Sam or another Developer of the game please refrain from adding your opinion, as valuable as it may be I'm not trying to rehash a discussion that will bury this post just trying to get a clear answer from the Devs..
Thank you
