Please introduce a threshold of wipes to allow leaving a duty without penalty.
I'm not sure why it's fair that I should have to choose between a 6th wipe *at the same mechanic* and having a 30 minute lockout.

No amount of explanation, marking a competent player or hopping in the spot of the safe zone of the mechanic made a difference.

Even making the penalty proportionate to the amount of failures would be a start.
