Battle Preset / Tactics
I think there should be a battle preset option where your guys know how you want them to move in any case where you aren't able to personally command them due to real life or loss of cellular signal. I don't think that your soldiers should just march forward every single fight - they should know how YOU want them to fight because they are YOUR fighters and YOU trained them.
This could be a simple preset for the first move OR it could be a complicated preset for each turn which includes the type of movement you want them to make AND the type of enemy that they should attack on each turn.
For example: A simple preset might be Cavs always go forward, everyone else waits. A complicated preset might be on Turn 1 - Cats wait and attack Cav, on Turn 2 Cats move forward and attack archers, on Turn 3 Cats move forward and attach Cats, on Turn 4 Cats back up and attack Troops - or whatever you like - including movement and preferred enemy to attack.
These presets could also destroy your army - which is why you still need the option to command fights BUT -- ALL soldiers ALWAYS moving forward is not cool.
Thank you for your time. =]
