Working in wings is best with people who have the same aims.
Just randomly joining up with others does not really work.
You need to trust your wing mates to watch your back and you will need to provide support for them.
Wing must have a goal or set of rules. Do you mind getting a wanted status or heavily damaged. When does wing decide to leave area? Separately or together? For example.
The same problem also occurs with crew. Only worse.
I don't think people are keen on joining as-hoc wings.
Get some friends to join you and go as a team. Then these issues can be worked out in advance.
