Why are NPC parties so bad?

[Thangil]

Trusts are like getting lunch at a big franchise restaurant. If you go to Applebee's or McDonald's, you know what you're getting. It's not the best food, but it'll fill your belly for a while. It's consistent and reliable for what it is.

Party Finder is like looking for smaller local places. There's a chance it'll be an absolute dumpster fire that'll make you want to rip your hair out, or it'll be a wonderful experience like no other. You won't know until you try it.

I have NEVER had a bad experience with party finder, other players are absolutely fantastic in this game. My issue with it over using NPCs is that you have to wait.
