It's kind of annoying to be out in an explorable zone and suddenly shout chat fills up with the "[Server] Train" of people from other worlds coming in to collect them all. Like if you're not part of the herd scooping up everyone's hunts, you don't get to do it. It was already annoying having people silently kill a hunt monster without telling anyone or tracking it, but now there's just no point in looking since they're never there because a bunch of people that aren't even on that server killed it as soon as it spawned.
