You lost me here. If, as you say, everyone would do the missions in free flight then it means no one wants the career mode. So why spending millions on developing it, why make consumers spend millions of hours grinding buggy, boring missions, if no one really wants it, and MS/Asobo won’t monetize it?
I do believe, that a properly implemented career mode would make sense for those who like that aspect of a flight simulator, proven by successful and popular addons.
But for those, who don’t care about making credits and profits, like me, please, let us get to the missions without torture. I spent many happy hours doing logging and HEMS missions with the Hype H145, and I love that you can just jump into the helicopter any time you like and do any kind of missions, just for fun.
