I wonder if this System is connected to the reinforcement mechanics. In other words: do all the lords in an Army have to start on the battlefield. Personally i think it would be cool to asign a lord or maybe even the Player to command the reinforcements.
If reinforcements are handled like in warband that would mean that every „command Group“ will only be reinforced by a few soldiers, right?
I think there has been some info about reinforcements (a blog?) in the past. So maybe my questions have been answered before.
