Wing mining missions would be cool but as per usual miners are snubbed in the updates.
There are some fetch request wing missions, I'm sure some of them ask for mineable resources.
Personally though, the cargo ones are pretty pointless. I can stack normal cargo missions to make in one jump what requires 3 or 4 with the wing missions.
As others have stated though, the BGS is all out of whack, Colonia missions have started popping up everywhere again. I'll give it some time and hope that changes things. If not, there's now a lot of broken things in the game is all I'll say.
