You're 100% correct that this is a problem, but talk about a misleading title. Maybe you should change it.

"For trained units, backswing should be triggered on a per-model basis."

Definitely agree. Somehow in my mind this was in the "so obvious it will be included by default in version 1.1" category, so I didn't post it myself. But good job. Definitely needs to be done.

While we're at it, can we get some feedback on how many figures in a unit miss? Maybe that would just make it too crowded. But when I'm designing dodge-based units it would be good to know if the low damage is because of misses, or what.

That sounds good. Anything that can add some clarity and depth to tactical combat. 

I know it has been asked for before, but it would be good if damage was limited to one guy, unless a special kind of ability was deployed ('sweep' or whatever).
