but that means no more mentor roulettes. on both dc's i've played on as a mentor, tanks get instant, and i mean instant, queues. throw on top of that the absolute highest content diversity of any roulette AND a high chance to join a party in progress and actually help people out, and hey, it's a pretty good gig.
insofar as toxicity, i can't really speak on that as i don't hang out in nn. when i was a sprout, i joined and it was awful, and left after about a day or two. no toxicity but everything was off topic and some highly questionable stuff was being said. overall the mentor system is fine, kind of unnecessary but fine.
