This might be a bit like cheesing the game, but I wish we could tell people more that we need to think about it.
Like when Zevlor for example asks me to kill the Goblins, I'd rather just say that I'd like to think about it to avoid disapprovals from party members then just go and do it xD.
I can see Lae'zel still disapproving on that because "You have no conviction" or something like that.
That being said sometimes, being disliked when you say the truth or what you truly think (especially when it comes to sensitive topics) makes dialogue realistic as well.
