Still a penalty to leave dungeon even when you stay past the initial 30 minute mark?

[ItMe]

What is an issue, is if people in a dungeon clearly don't get it and continue to make the same mistakes even after being told several times, and everyone has already spent almost 1 full hour in a dungeon that normally takes 20-30 mins, then there should be no 30 minute lockout on duty finder.

This could be useful during times when kicking them is not an option.
You shouldn't have to be stuck between a rock and a hard place just because you don't wanna carry someone.
