I would like to suggest the option to be able to retreat your units from combat.
How it works:
- When your units are in combat, you have the new option "retreat".
- Unlike "move" command, when you select "retreat" your units will stop fighting, and will have to wait for the next enemy attack(s), already in progress, to resolve.
- After you suffer the last hit from the enemy units, your army will detach from combat and continue the movement.
- Enemy units what were engaged in combat should be stopped for a while (5 minutes for example) so the retreating armies can actually escape and make a distance from them, in case enemy units also had the order to move in the same direction.
What do you think?
