Suggestion: Make Mentor Roulette 2k Achievement Mount 'Time in Duty' Based
What if the mount reward from doing 2k Mentor Roulettes was 'time based' instead of based on the number of completed Roulettes? Make it so people have to spend 60,000 minutes in Duties via the Mentor Roulette.
Toxic/Selfish Mentors gain no benefit from rushing/pushing Sprouts into completing Duties as fast as possible, nor do they gain any benefit from dodging Duties that are guaranteed to take 30+ minutes.
As long as the timer keeps ticking, giving Mentors incentive to not simply rush though a Duty also incentivizes them to actually attempt to teach Sprouts.
