Busy indeed ..
It will be set back to how it was in WOFF 2 in the next update probably V3.4. You should be doing what the CO dictates that's the idea but anyway...
Optional flight just gives you the same mission type, just different target of the same type - if available.
Alternative target changes the target type - if available.
However you will be able to go out to campaign screen and come back in to get another random mission type. This of course, being random, could give you the same type as last time. It will also be dependent on the squad's role - some have limited mission types. Some for example will mostly be patrol, with some balloon busting, intercept whatever from time to time.
If you allow me to insert a GUI mission editor (when it's ready) inside the campaign, then the player can alter anything like pilots, targets, waypoints, altitudes, etc... It just requires that the editor can access the "OFF_Camp_Mission.xml" file before the mission is launched and player spawns on the field like it was in WOFF V2.
