CS farming?
It could mean moving between Penitent Waypoint, Shelter’s Gate Waypoint and Jofast’s Waypoint, to do the quickly-repeating events for karma and drops, or it could mean farming the water south of Anchorage Waypoint for the tier 6 crafting materials that are needed for crafting legendaries.
If they’re looking for a group, it’s to move from one GDE to the next, using MF banners and food to get as much money as possible.
