I'm sorry but if me or my friends see a hunt, and no one is around, we arrange a group ourselves of whoever wants to join, and we will start killing. I don't even hunt. It's just if I see one while I'm doing my business of gathering, queuing for whatever.

This is how the system was intended, not for the whole server to appear at once and kill it. It's utterly ridiculous. I'd like to reiterate that I do not actively hunt at all, I won't descend on the hunt myself if people are calling for it, it's just if I see one on my travels.
