Scouting being (very) limited means it's not very useful. The only truly useful thing to scout is traps, but given that there seems to be no pattern to how traps spawn I can't test likely options; even with 4 scouts there are far to many POIs to use. So every POI is a roll of the dice as to whether some of my roster will be out of action for a month. There's no way to mitigate it other than just avoiding as many POIs as possible.
