As for why we're the de facto leader, it's a cRPG, and someone has to do it. I couldn't begin to imagine the outrage if we were suddenly just a grunt, and were expected to do what one of the other party members wanted to do instead of playing the way we want. I will say that it's another of those situations that will require a metric ton of popcorn though. As to why comps don't react to a lot of stuff outside of what you chose, I'm pretty sure that would be another case of needing lots of popcorn.
