Either remove MSQ roulette duties from Mentor Roulette, remove MSQ roulette duties entirely and make them actually MSQ-tied like they did with the Final Steps of Faith, or remove MSQ Roulette (And the constant mogstone bonuses for its three duties) and make it so that it isn't in any roulette other than Mentor.
I would preferably take option 3. That way Mentors are still able to help and people are able to do it premade, but only people that actually need it, or want to do it for the duty itself, will be doing it.
