I have read most of these and I agree with a lot of the ideas. I would like to see more with the other companions other than the first in terms of going on the missions with them. However in that respect I also think it would be fun if you could temporarily take control of that companion (ex. Kira for the Jedi Knight) to do the mission. In the two KOTOR games you had at least one mission where that was the case. So maybe the character you created does not go on the mission with them, and an other member of the crew goes instead. This is just a thought and something that I think would be interesting.
