By simply entering a dungeon or mission it automatically consumes one of your daily limit. That’s a ton of exp to miss out out over a simple mistake, 1 extra button press with a controller and you’re screwed.
Why not change it to lock you to an entry after a boss or monsters are killed or have a 30 second grace period to leave, the dungeon doesn’t technically start for upwards of 45 seconds to a minute anyway. I’m not talking about party search, just the standard solo or pre-made team entrance.
