It seems like some common courtesy would be good for everyone.
On Behemoth at least there are two people that everyone that hunts know will rush in asap and pull it before the main group has a chance to arrive every single time.

the friggain things take like 4 hours to come back and are designed in a way that they can give full credit to everyone.
waiting half an hour for the whole world to finish what they're doing and show up is certainly not expected but giving the giant group that is actively hunting 30s or so to collect is not that difficult to do
