What’s up with players in dungeons.

Is this like wow where you’re better off just doing everything solo or with your guild/ FC and not use the duty finder?

Nah. Playing both here and on WoW since 1.x came out, XIV has had the slightly more toxic Duty/Dungeon Finder experience, but no matter how you look at it, you just got some 30 runs' worth of bad luck all at once. This is an outlier.
