I might be in the minority but in my eyes a mentor is just another player, I am not going to hold them to a higher standard because they have a crown next to their name. You run into helpful people and you run into not so helpful a crown has very little to determine that. Personally I think people expect far too much from "mentors" and by no means do I buy that they should be held to some paragon standard, Mentor system was simply SE poor attempt to provide an incentive to prompt generally good favorable behavior. In SE fashion they try to bait players with carrots. Oddly enough most mentors I ran into simply went through all the hopes to be part of the closest thing FFXIV has to a general chat in game.
