The majority position is to languish in mediocrity, so that's not what I'm getting at. I'm advocating an ideal that's neither especially popular nor enforceable.

Given the circumstances, you are very likely to run into people who have run the same dungeons more than a couple of times for a specific purpose. I don't think it's significant whether they've done 20 runs in a day or 20 runs in a month; the rote, unproductive repetition is demoralizing and time-consuming. If I were in their shoes, I wouldn't want to spend any more time than necessary to slog through the dungeon again. That's how I see it.

Someone with a bad attitude or someone who doesn't feel like it? There's really no argument for that. All I can say is "bummer."
