The other 3 players would love to watch you idle in the city and salvage stuff, combine gems and just arrange your items.
A way to improve this experience is to join public greater rift games and just decline any kind of rift start since there is still some sorting to be done.
I need to adjust my pace based on what's happening with real life demanding my time, which is an annoying part of being a grown up. I might chain run half a dozen rifts without even stopping to sort loot then spend 10 minutes idling around town before the next one. Easy in single player, nasty in a group.
