I think you misunderstood. I'm talking about the Duviri Experience, the option in the middle which is the equivalent of the free roam option on the Plains on Earth and other open world place. Being salty about people doing puzzles in Duviri Experience is the same as going into a regular free roam, starting a bounty then getting mad no one helps. The Lone Story is the mission oriented version. That's the one where I've seen most people farming pathos clamps.
Also, and very obviously, not everyone does Duviri for pathos clamps. Like I already said, most of the people I've run into are doing stuff besides the Undercroft in the free roam mode and as others have said it's a starting area for new players.
Maybe you are the one that should be solo if you think other players are "hampering" you.
Unlike some people, I'm not a misanthrope. I enjoy playing free roam with other people in a CO-OP game. I also don't mind running the bounty while my mates fish or whatever. But Duviri is the only open world area where everything gets completely interrupted.
