Just curious how many units can partake in a battle at once and if there is a way to get them to show up all at once? I was under the impression that we could have our entire army on the field at once.
There are a few mods that extend the battle size to 1000 (in Native, the "Battle Size" slider only goes to 150). The Battle Advantage number has a lot to do with how much of your army participates in the battle, too.
