Solo Friend Found

Suggestion:

Create an option in SSF to invite X number of your friends (from friend list) into a SFF (Solo Friend Found)

Where you can only play with the group of friends you started out inviting to your SFF at level 1

Then in endgame you can run together and share loot/currency

But you can still not interact with trade league/Trade Site etc.

Or guild members etc.

Would keep a lot of the SSF feeling, but still make you able to play coop group play with a few friends

(Yes I know you could just agree to not use trade site and currency exchange etc. But hey its human nature we are talking about here).

Share = trade
Would be nice to party with other ssf player though.
