You are 100% correct. Every day is harder and harder to create missions. Every new plane has more and more tabs to configure, many new "features" complicate that even further (DTC, VOIP, etc) and there is not a single improvement on tools to help the content creators. Starting from Mission Editor (2025 still no undo), to how you configure weather (fog is a mess), to replays, broken/unfinished VOIP, DTC, etc.....
I am afraid the will launch DC so unfinished that it won't serve it's purpose.
DCS planes are beautiful but this company have forsaken its main value, the community. It's hard to see how would they reverse this, specially after latest leaks.
