AI is not ready yet, so we do not know what will happen, when it is ready.
They probably decide individually, who does what for now.
So does the AI make a group strategy or just runs characters by order of initiative and decides what to do?
If the AI would be able to see what happens beforehand, see the damage, that is about to be calculated,
and decide the next action based on that for the next character. it is okay.
It is also an option, that they move together to attack someone even if one of them was enough, the other one will just
move to the new target. After all in battle you do not know what happens in the future, who will be killed or not, only in turned based,
how much soldiers you need to take on someone.
Also we do not know how AI affect performance, maybe they also take half second for each stunned people in divinity 2, because
they need some time to calculate the action of the next Character in big battles.
I personally would not mind a bit unbalance in AI if it could make a 1 hour battle 30 min long.
