There is one tiny problem ...
Imagine you keep combat runing while anyone is downed ... you use help, and he stand up with 1hp ... no one downed, conversation started ... but that one character is poisoned, or standing in fire, or is Astarion and is standing in water ... and while you are talking, he is once again dead.
Autostabilize out of combat on the other hand, keep your comanions relatively safe ...
Better option here is simply let players end combat manualy ... when last enemy dies, you simply switch to forced turn mode, difference here is that in this case player is the one who decide how many another rounds he want to have ... that way player can heal all his companions at will, and place them on safe ground ... and then care to other matters.
Or there is one more option, potentialy best one, but i gues it could meet certain multiplayer problems ... and that is concidering whole world around conversations to be in turn based mode ... and acting in single turn while conversation is runing, that way none of your companions can die no matter their status, or enviroment.
It would also be solution for some stupid situations like in mage tower, where your main character is talking to Bernard, and other characters are allowed to run around the room and even start combat with his helpers. :-/
I still dont understand why cant we change Race for our hirelings.

Lets us play Githyanki as racist as they trully are!
