The little "group" I'm in is a few of us that "met" playing WarThunder.
What we do is, we camp a nav beacon at an Anarchy system, and K-scan all NPCs and kill (or attempt to) any of them that have bounties. 2 of us are in "fighters" (a viper and a cobra) and one is in a hauler. The other fighter pilot and I split the bounties, we widdle the NPC down to low % and who's ever turn it is takes the last few shots to get the bounty (we always use TeamSpeak for voice comms, so coordination is easy). And the player with the hauler scoops up all the cargo that the NPCs drops. Its a pretty good little racket and all 3 of us make decent credits, and more importantly have fun. The most fun is encountering a hostile player controlled ship. He shoots at one of us or kill steals too many times, and he doesn't realize all 3 of us are working together in teamspeak, and all of a sudden he has 2 additional player controlled ships directly on his tail spraying at him

We all came over from WarThunder so air to air team combat is what we like, and that seems to have translated well to space to space combat
We play Open play and never once have we not been in the same "instance" (i.e. server) when arrive at the nav point. I think match making uses your friends list as one of the priorites for placing you in the same instance.
I tend to agree that "team" play is so-far lacking in ED. You cant "share" missions, though there is a youtube video of a small group of players taking down one of the 150K bounty targets together you get from the bulletin board missions. Im not sure how they all got in the same instance to do this, though I assume they are using the Private Group play option and used scanners to locate where the original player dropped out of supercrusie to attack the bounty.
Anyway, this is the first Ive heard of "wing" and hope it brings some cool stuff.
