One related point :
At the beginning of the Beta, it was advertised that we would have FULL flexibility during dialogues, including attacking NPCs when we first meet them. I even remember some cinematics.
And I really liked that the option to attack someone before or during dialogues, was not abusing the system but an inherent part of the game that could be roleplayed.
At the moment, all the main characters are now protected from such action and i dont think it adds anything to the game because the story has already proven that it does not suffer any premature death from main characters.
Would love to see the option to kill NPCs when first meeting them back at the release
