Surely the logical thing to do is take some elements of the wing mechanic the rebuy mechanic and then stir it up with instant teleport recipe.
Here is a scenario.
Friend invites you to be crew member on their ship called BOB. You instantly teleport into their ship. I doubt this will be dependent on being in station. It would just be like a wing request.
Your ship LAURA returns to its last visited station
Players on BOB are now treated in same way as if in a wing sharing benefits.
When one player decides to leave the ship/wing they revert back to their ship located in the last visited station. So I would end up docked in LAURA. [big grin]
This has the benefit of allowing group gameplay which encourages players to get together and have fun together, at the same time it stops what would be an exploit of one person making a journey while the rest just crew up then leave and insta teleport their fleet to the new location.
I find nothing gamebreaking about this too. Pretty accessible and logical with no exploitations and downsides, other than some people obsessing over the physics of it all.
The only better solution in terms of immersion for me is the dedicated multicrew player group option as a separate main menu selection but that one has the possible downside of trying to meet up at the same time with your crew to play. Another downside is the ship size because, if the group is formed of four people and the host has a four person ship, everything is peachy. If the host decides to switch to a cobra mk3, what will happen and who'll get kicked? This means there has to be groups for dedicated ships.
This sadly renders the 'hop in, hop out' multicrew, the only logical option which will enable more people to participate in it.
