If Act 3 could get more dialogue and camp scenes from companions, especially from the companion you're romancing, that would be sweet! It would be nice if act 3 was similar to act 1 in terms of companions having amazing dialogue packed throughout the act. Act 2 is fine because it's such a short act that it doesn't feel like it has quiet spots. But act 3 is so huge that it can feel too quiet. Companions seem to care less about you or what's happening than they did in act 1.
