When multiple players are hunting in a world, the PP targets are quickly exhausted, leaving all parties with barely anything to make it worth it. It would be a good idea to add more instances of worlds to hunt in.
Alternatively, you could make PP targets per-player (player A destroying a target would not destroy it on player B’s screen). Then players sharing a mount could share PP targets, so the PP can be shared too. Not sure how that would work for dropped giftboxes, though.. Probably easier to just add different instances of worlds
