Is there any way of changing the way that the computer prioritises who fights who in a stack. I assume that the computer just choses the best attacker to fight the best defender in a stack. However, this means that quite often an injured hero unit has to face a likely death from one high level attacking AI unit while less valuable units stand by and watch. For example I landed a sizable stack next to an enemy city, amoung other various units I had Bambur and three Shield walls. The shield walls were there to protect the stack but as Bambur was at level 13 or 14 and had various promotions the AI attacked him until he was dead, while my defensive units did nothing. needless to say the AI lost the overall exchange as they had lost their top units taking out Bambur and I was able to take the city easily in the following turn, but Bambur was no more. Is there a way to force defensive units to be the first defenses of a stack?
