That's "mean world syndrome," in which media tends to amplify the negative and make it more commonplace. I don't see complaining, I don't see mass bad play, and the only time I had to abandon a casual duty was rab and royal menagerie when they were brand new. Dungeons I never see issues, trials i never see issues. Casual play is fine; the real griping tends to be in 8 man ex pugs and up, and people wanting as quick and as easy clears as casual play.
