Why not increase the gang cap to 50 then have options to just create parties with whoever. You click the player and click the more actions button then click invite to party. When you invite the first person to the party you become the leader only the leader can kick and rec. When the leader gets off the 2nd player in the party becomes the leader or it just disbands.. Party wont have names they will just be something that allows you to work with your friends. Could have a limit from 3-5 Could have options to enable exp sharing,Could have a party chat button, Could summon each other.
