To be honest, where does this idea come from that mentors must be these perfectly behaved angels of human beings? None of us are, so stop acting like mentors must be perfect all the time. And as to why a mentor would quit a Ramuh extreme? Well, I've done 2000 mentor roulettes and as soon as I did my 2000th one, I almost burned down my computer so I never have to see the two words "Mentor Roulette" ever again. Sprouts are way more disgusting than any of the mentors I have seen in my Astrope run. Self entitled asshats who think mentors are there to carry them and literally waste hours of their time on content you should not even be queueing for at this stage. You want an extreme clear for a primal? You make a party finder where you do it unscynced. And if you do want to experience the fight synced, then you make a party finder. In my 2000 mentor roulettes, I have probably wasted hundreds of hours teaching people extremes when they are dumber than a disabled chair. Think of that the next time a mentor quits an extreme primal. They are human too and you will do well to remember that.
