I agree that this gets abused. My recent experience was in Halatali HM. I said before the cutscene even loaded that I hadn't done this dungeon before, and I needed the fights explained. No one explained anything until after I got killed by 1000 tonze swing. Got killed once by Demon Eye, and booted.

If someone asks you to explain the fights, and your response is to boot them, that's B.S. At minimum the abandoned duty timer needs to not be used against you.
