Please change the requirements to become mentor

This. It should in no way be a means to get loot. That's the root of the problem.

I'd say the problem was more the tying the roulette to the mentor system, because that's where most of the friction comes from. If someone is rude in the Novice Network, they can get kicked and you easily have logs to report them. But if a mentor bails on a roulette, how do you deal with it? They were already punished by the built-in penalty. They explicitly said the roulette was there to fill up queues, but at the same time the Mentor's own guidelines requires so much more, and it's locking the dual pony behind it. Problem.
I agree with a notion that was brought up earlier - break the roulette away from the Mentor system and turn it into Duty Roulette: Veteran. A lot of people who'll run it will still be helpful and actually teach. The many who won't won't get half as much flack for simply playing their role (mind that elitism and toxic behavior should still be reported). But it will certainly tone down a lot of the friction that comes from the roulette being a Mentor thing. Lots of Mentors don't even run the roulette in the first place, anyway, and plenty of roulette goers couldn't care less about the NN.

I'd agree with all of that, yep. That would solve a lot of the issues.
