I'd like position markers (like the home zone, only one square size per click) to be occupied if attacked.
So you build a sand barrier and mark three squares behind it like this.
If an enemy attacks, three fighters try automatically to man up these positions.
Additionally a retreat zone, where non fighters retreat to, while an attack is occuring.
With this you can build some tactical defenses before the fight and don't need to micromanage
everything manually while the attack occures.
OK, I'm not sure if this really qualifies as a
cheap idea...
