I have had some situations when planning missions where I planned a Sea based mission in the island map, then found on squad night the map changed to the lake map. Any mission with GVs can be a problem if you end up in a map like Mindanao.
I don't have any problem with coming up with a mission 10 minutes before briefing, but it seems our squad has better turn outs when I can post the mission a few days in advance. It helps to know what map we will be playing on.
I agree that specific targets can not be set in advance, but knowing the map will give mission planners more options for missions.
We also may find that there are only 2 fields to fly from, but that's a subject for another topic.
