I am unable to find a way to switch characters in coop without having the other player drop and then rejoin after I have selected the one I want. Character selection should persist through a reload.
If rearranged, the portraits on the left of the screen do not seem to retain their position after a reload. Perhaps the hosts controllable character could default to the top most portrait as well.
I also do not enjoy my screen being moved around during combat to center on who is currently moving/attacking, etc. I would like an option to turn this off.
During a game last night my coop friend became charmed and I was forced off of my character and onto Madora, and he was given control of my character. It would make more sense to me to have given control of Madora to the charmed player instead of shifting both of us around, or simply leaving the charmed player as is until the effects wear off.
