OK since this keeps becoming a thing lets break it down shall we?

First, you won't be 'mentoring' how to do alexander ANYTHING most likely because you can only be in the mentor program (as a student) if you are under 40 hours into the game. The majority of mentoring will be more about how things work (example: how do I unlock my chocobo?) then it will be about shit like a dragoon doing optimal dps at 60.

Second, mentoring is completely optional. Stop being so upset that you don't meet the requirements for it, if you want to help people you still can WITHOUT this system. There is literally nothing that will stop you from taking a new healer/dps/tank who wants to learn how to play their class the correct way and teaching them everything you know, if you are both willing to teach and they are willing to learn that is.

Finally, and most importantly, the bad attitude about a system you don't meet requirements for that isn't even released yet will only sour the image to any new players that actually might think about joining it. You need to be calm and level headed to be a good teacher, and if it upsets people so much that they have to disparage a system because they can't use it, you probably weren't going to be a good fit for it anyway.
