Interesting functions parties and clans should have

I was thinking that parties right now are a bit bland, so first add in a option for players to let party members pick up loot, then make it so people who chose different classes will be able to unlock skills for party members, like mages let everyone teleport to each other and warriors give extra hp or dmg so on and so forth.
Then there is clans, and they should be unlockable for any player if that player works hard enough, or by robux, the clans should allow similar abilities as parties, but on a larger scale.
