Cross world hunts have made normal hunt trains go into slow-mode to allow more people to show up and that's just a downward cycle that feeds on itself.
While hunt trains as an idea is a questionable thing already, I'm not one to bite the hand that feeds. They were fine for a long time, a quick trip around the world for some easy tomes.
But now there's conductors that will intentionally send people the wrong way in order to delay the killing to allow more and more players to pack into the zone. All it really does it stop local players from accessing the zone, both hunters and people that just wanna go about their business.

If you wanna disrespect what hunts are and create a train, then bullet train it. I've essentially stopped hunting due to this.
Unfortunately it's player made issue based on a SE made problem. While it's the conductors right to set up as they please, they can actively make the game unenjoyable for some depending on how they do it.
