Having stricter requirements means those that pass said requirements are better suited to meet a higher standard. volunteer positions do not mean they have to take anyone off the street.
Bobby: Ill be honest.

I have met nurses who had the personality and skill of a teaspoon ( we used to have an old axiom that the nurses who went straight in administration after graduation did so because they couldnt hack it at the bedside) , I have met people with multiple degrees who had the commonsense and communication ability of a runaway Mack truck.

My point is that it doesnt MATTER if they have beaten all the savages, all the extremes, pvp, tests whatever..NONE of that means they will be able to , in any way shape or form,. teach, tutor, assist. Being a craft mentor doesnt mean you dont know combat jobs either. The key element here isnt whether they have met all these pre requisites because they will STILL suck at people skills.

Actually its hysterically funny in one sense because what you are espousing is the old US trope that having gone to college means you are smarter...it dont, trust me. Having a degree doesnt mean you know a damned thing, all it means is they have a piece of paper. Its what they can..or CANT..do after that being the acid test.

Doesnt matter how many tests etc, they do how many savages or extremes, if their response to a sprouts enquiry is "Google it"? They are next to useless.
