I like it personally, it lets me get into character more because I don't have to say something my character wouldn't actually say. Instead I can choose the tone or implication and fill in the blanks with my imagination.
I don't give my money to RPG developers so that I can then write the dialog for them.
I give it to them assuming they will hire professionals who will produce something beyond my skill level.
Larian went and hired one of the best in the business.
And then they turn around and give us what is to me, the worst format for dialog ever to appear in an RPG.
I hate it.
Spam 1. and hope for the best is the only option right now.
