I rather like that idea. Almost like meeting a quota. Regardless I'd agree with the idea that square needs a secondary filter once you are actually a mentor. It would take time but with something like that in place at least it would filter out those who might be a determinant to the community and new players. I can't speak to the status of the chat itself but I have run into a mean spirited crown bearer or two in expert roulette oddly enough. But lets face it, those people were mean spirited before the crown just like there are plenty of people genuinely trying to use the mentor tools to help. The community hasn't changed.
I'll admit to being one of those miffed and suspicious of the whole idea. I didn't meet requirements thanks to leveling different classes on alts since launch and I was rather worried that with the introduction of the mentor system, those of us who didn't meet requirements would be at a disadvantage trying to help new players since they would likely turn to mentor roulette and chat over leveling roulette etc. But nothing has really changed for people who still want to help. You can. You can do leveling roulettes and I still see sprouts there and checking the entrance to the low level dungeons is often a good spot to find new dps stuck in huge queues *shakes fist at dps queues*. You could even gather a group of like minded, experienced players and create a linkshell in the spirit of the mentor roulette which is frankly what I'm considering doing on Balmung. There are a lot of options out there and in the end official mentors and those who help without the crown are really fighting the same fight and probably equally upset with those who are abusing the system. In the end we can only hope that the good experiences out number the bad for new players.
