I've seen people straight up afk next to the fate train (including group leaders) and it can be frustrating. I understand low level characters not wanting to get involved with higher level mob farms, because they do next to nothing damage wise and can die very easily. That's what I've seen more of. Best to just stay out of the way and let the higher levels do their thing until the fate spawns. Some people genuinely do have to AFK during fate spawning, it happens. Done it myself a couple times. But people who are blatantly obvious, mounted up and everything...come on now. Do things die in seconds? Yes, but at least contribute.
