I don't mind if the animations for the auto-resolve look odd or don't match what would really happen. Once I had a group of Shaman mercenaries deliver the final blow to the enemy after every other allied unit was dead. I thought it was amusing, but it's not really something that needs to be fixed. It's an animation.
It's only when the autoresolve calculation does something odd like this - Troopers beating Imp fighters, or a lone Trooper beating 2 Hunters and 2 Armours that it's a bit bothersome.
I don't think that the autoresolve plays out an actual RTS game invisibly, and there's certainly no possibility to review it to see what happened.
