I do wonder if there's a fundamental difference in attitude with regards to normal mode content that's causing some of the conflict here.

For a lot of players here dungeons are a daily chore they only do to get tomes to progress on the content they actually do enjoy.

For a lot of casual players dungeons and normal mode raids are the game. True, maybe they wouldn't queue if dungeons didn't have a character progression reward tied to them but saying they aren't any fun at all seems unfair.

I'm not defending players that don't try, but I don't think there's anything wrong with not wanting to rush through the content as fast as possible.
