I wasn't referring to the unit spacing when Idle, but to the actual combat spacing itself. Not sure if all WOF had the same combat spacing though, but the ones I compared was only the extended version and the Ancient Empires combat system for Attila, which was the one placed in the steam workshop. And combat spacing on both mods looks different. From the looks of it, the Ancient Empires version in combat spacing looked a bit the same to vanilla. Speaking of vanilla, here's some sample shots.

The thing with WOFE's version, battles just feels more organized, compressed, and you can actually see a line in the middle that separates two different units, while not even a single guy will slip through the ranks because of how tight the formations are. Overall, battles just looks simply stunning in WOFE.
