yo question would there ever be a possibility of a "party system", meaning when you and group of friends actively hoping worlds or as every party person calls it "drinking adventures". one could create said party and invite them to a party and when leaving a instance it would invite a people to the new instance, for example how furality did it on there webpage on the event days for smaller groups to join one another with in these parties and the host could include a listing of worlds via new button "add to party playlist" to add worlds to visit.

this is probably a long stretch since groups are a thing but for a more small group party concept it would be kinda cool. :P
