The currently mission editor does a pretty good job in the MA,it allows one to create an orgainized attack on and target and provide the aircraft and load out for an airfield or VH or other target and provide a basic profile and route of flight.
The current mission editor/creator has many drawbacks and if/when a mission arena is created the current mission editor's short commings may cause what I hope will be a welcomed addition to game play, may in fact be little used and quickly fall to to out of favor because of the problems with the current Mission editor.
A mission editor needs to do more then is currently available with the current editor. A Mission editor needs to be able to assign flights, flight leaders, aircraft, aircraft load outs, routes of flight, waypoints(by name), call signs, radio freq, missions load outs, primary targets, secondary targets. Target maps should also be available.
The creation of a Mission and the start of that mission should not put pilots in the plane on the runway, as it now does. The Mission start should lead to perhaps a briefing room in which mission members can discuss detailed assignments and review target locations at that point the Mission leader can launch the mission.
