I fucking hate these bloody "tone" responses. Who ever said paraphrasing responses was a good or even elegant design choice? I think the original idea was that merely voicing lines which are already up on the screen was too redundant, but I take redundancy over potential confusion any day of the week. Besides, I never heard anyone complain about the way dialogue choices were handled in the Witcher games.
It's a role playing game for heaven's sake. I cannot really role play if my stupid character says shit I didn't want him to say because picking "sarcastic" as a choice can mean all kinds of things to all kinds of people.
Isn't that basically what FO4 did? I agree with you, I don't like that one bit.
