Additional penalties for mentors insta-leaving dungeons?

[HakuroDK]

I'm a mentor, I wear the crown with the responsibility it puts on my shoulders. I'm gonna do my damnedest to help whoever I can, even if it causes them to kick and scream and cry like a small child. That's what I signed up for. If you can't take the heat, turn off the crown and stay out of the mentor program.

I think there should be additional penalties for mentors leaving dungeons: A demerit put on a mentor's record that remains there for a month. If a mentor gets enough of these demerits, they lose their mentor status and have to earn it back by completing Mentor Roulettes in succession. Not all at once, but don't expect to get your mentor status by doing the same stuff you did to lose it.
