We seem to have a fundamental misunderstanding here.
I have no problem with anyone enjoying the career mode. Go ahead, have fun, have your rewards, I understand there is demand for it.
However, I have no desire to do boring, frustrating work (yes, it is work, the worst kind, the one you do not enjoy, i.e. missions I do not want to fly), to access missions I do want to fly.
What is the reason I’m denied access to them?
