I've been attempting to do some hunt trains lately just to speed up getting nuts for tome gear upgrades and it's... Been mixed.
I appreciate the people who do trains that wait a minute each area and make sure it's not congested so everyone can get there. But a lot of them were "join and if you can't get there, don't bother". Which sounds like it would only be a lower end system problem, but I have a brand new gaming computer and even mine struggled to get me there at times because the aetheryte would become congested, even from accepting a teleport from a party member. I've noticed there's been a few "locals only" trains and these run smoothly, and remind me of when I did trains back in Stormblood before the cross world. I like hunts, I just wish they weren't such a mindless pain in the ass to deal with.
