The problem with the mentor system

[Neoom]

You can be a mentor in full gear on an unfamiliar class and be tunnel visioning so hard you miss mechanics. Not only can this be a thing but I'm pretty sure every mentor and player knows exactly what I'm talking about, first hand.

^This, since as someone who used a lot of time to max all classes to 80, I still don't know all of them better than basics of the class. I don't have full rotation or how to play on lvl80 content as that class to the full potential. For example, I play casters 99,9% of the time, mostly healers. I know how all those 6 work and to play them to their max potential on 80. But I can't wrap my head around any of the melee classes no matter how I smack a dummy, but it's fine since everyone can have a main class right? Even mentors. Me having all to 80 doesn't mean I know all the jobs perfectly and will put out the best dps no matter what class I play, it means, I had time in my hand and I like leveling classes. I don't have to know all them, only the ones I play more than often. But I can still go mess around in casual content as a melee and try my best to do well, but I can't be held against a wall and say ''You're a mentor why are you so bad at samurai???''. Everyone will play random classes to mix things up every once in a while, even mentors. They aren't perfect 100% of the time and on all classes they max out, and that is not what they agree on either. Being an example doesn't mean ''Be 100% perfect and know your rotation from start to finish no mistakes''.
Let mentors make mistakes, they're human too, just like everyone else. And before this is taken out of context, I don't mean mistakes as trying to sabotage or purposefully ruin the duty.
