Agreed. Wings as a properly implemented multiplayer mechanic is an absolute game changer. Even though I didn't buy ED for the MP aspect, I really enjoyed flying with wingmen so far and I know there are many gamers out there who do care a lot more about multiplayer than me and therefore will be absolutely delighted with how 1.2 turned out!
The best thing about the Wings system is that it can be made and broken as required. You can join up with some people for an evening and then you could all go your separate ways without ever seeing each other again. Or you can 'friend' with them and hook-up on a more frequent basis.
It is completely flexible. Great! 8)
