I think that would have to wait until after the new dynamic campaign, then they can gut and redo the “virtual pilot” portion of the sim so that it is more compatible between SP, MP and the dynamic campaign etc. Right now you can’t really select the pilot profile quickly etc.
For example maybe we’d want a pilot profile to lock in to a specific dynamic campaign. Then the campaign may end if the pilot dies (an option, like it is now) but you can’t change pilots mid-campaign even if they can survive by user option of “no death”.
At the same time you would want to be able to select a pilot when starting a MP flight, which should not be able to die as all kinds of MP issues could make that experience otherwise miserable. As well do the MP pilots stay with the player/DCS accounts - so you can take them to any server? Or do your stats get kept on each server separately?
At the same time in SP, they could potentially set things up where training missions are locked out and open up sequentially as a pilot profile completes them or “qualifies”.
I like the idea of pilot stats improving but that definitely requires ED to really rebuild the whole RPG aspect of things in to the game, which @Franze has talked about before in other discussions. A wishlist item for sure, we just need some foundation first to put it on top of.
