The battles are going to be massive chaos. Over at .com when I said the higher speed had reduced the ability to coordinate units, I was told I'd just have to increase my multitasking ability. You're going to have to increase your speed of managing the units by a factor of 2 to recapture the level of control you have in MTW. As far as I can tell you've also lost the ability to rotate units. Have fun redrawing the units when you want to change their orientation.
