Let's face it Mentor roulette exists just to fill back log queues to help the queue system. If you can't understand that by this point then there is no helping you. Skill or knowledge literally does not come into it. I'll never understand why so many people get upset with the Mentor crown. If there is someone in your party with a crown then congratulations, you just got a faster queue.

I wouldn't even say remove mentor crown / roulette as it's fine as it is. It helps the queue and sometimes you actually get lucky and get people that know how to press buttons or dodge aoes.
