Just a quick question... what's the most natural way of saying how much to leave troops behind when advancing troops?
For example, you want to leave 2 troops on the starting territory.
"advance all but one"
"leave 2 on <territory>"
"leave 1 on <territory>"
Feel free to add your own wording, I do think the first one is most logical because you can't move your last one out of the territory. So everything except "advance all but one" is illogical and can lead to confusion.
