There needs to be dialogue options altogether. So far we only see two for decision making. Where is the "I'm not sure" one? Where are the role-playing dialogues and witty dialogues for your character to say?
Well from what I've been hearing the key-words are temporary.
Concerning the disputes between companions. I think only a third is needed: "I'm not sure" otherwise you'll either agree or disagree. I guess you could add a "I don't care" or "I'm not getting involved" into it too.
