Ok, that's somewhat useful but waaayyy lamer than I had thought.
Alas it is true. Would be nice with Stats L4 to see the # of units required to conquer unrevealed territories. It gives a good frame of reference for just how much longer it will take to clear the level - which should not be hidden imho.
Also note sure why these stats are under "Level Stats" on the AP Advancements tab. AP Advancements tab should be for upgrading AP Advancements tab, not for using the benefits from AP Advancements tab. These stats below in the standard Money(￦) and Army(₳ ) mouse over pop up areas, so they are easily viewable, instead of having to do a couple clicks to get it.
