I agree. Some activities involve countless hours of boring grind but a single ding and a platinum achievement showing up somehow makes it retroactively worth it? Same can be said for people who do [dungeon] 10 times because it's 30 seconds faster. Like, nah. You either design it so it's fun to do or you don't put it in the game.
And XIV should take a very hard look at DR and dungeons among many other things in that regard. I'm sorry, but if you think running the same dungeon again and again while pressing AoE #1 and #2 is fun then you have no taste. It's the RPG equivalent of white noise. It's okay to have it I guess, but it shouldn't be the primary source of "entertainment".
