Unit Counter?

[FrozenFear80]

I recently received a post-match tip that said I should pay attention to my "unit counter" during battles in order to succeed. Anybody know what this refers to? I couldn't find the term "unit counter" documented anywhere.

I believe it's referring to the bar in the bottom-left of the screen, it'll show how many units you have on the field. The more you have, the longer it takes to build a new unit.
