The world is very big, 1:1 is a big scale to give both charts, waypoints, ICAO codes and other flightplanning. For example: missing oil platforms for offshore missions like: ENQA Troll A, ENGA Gullfaks A, B, C.
And I also missing the feeling to custom make flightplan in simbreif to make routing and generate it simlar to IFR routing with airliners. Then you got a 100% flightplan base to fly as quickly ass possible both VFR and IFR.
