I just wanted to state out that many world map battles are between two groups of (escorted) merchants, which doesnt fit that good IMO, If it is possible, it might be more logical to change it so that always at least one of the battle participants is not a merchant, but also not e.g. a Battle Fleet against a merchant. I dont think that merchants of 2 nations always tried to fire on each other at first sight, or that a whole Battle Fleet wastes their ammo for a few poor merchants.
