I'm getting so sick of being booted on the last boss of a dungeon, then being forced to wait for the "leaver" timer even though I never left. Doing all that work and not getting the daily clear, not getting the potential mask drop, and not getting anything from the dungeon at all. By the time you log back in either the dungeon is cleared or you have been kicked for "logging off". This isn't something that players can control and I've seen it happen regularly with randos as well.
