I would like to see something that allows you to choose the character's stance for battle "rules of engagement." I feel this could enhance the game, as well as stay within its intended "squad based rpg" style.
For example, something that allows me to select "Stand your ground" to not move unless the enemy gets within sword's length.
Or when auxiliary weapons become integrated, "Hold your fire" could be a selection.
Food for thought!
On a side note, I need a ninja smiley. This is blasphemy.
