Frankly speaking, we live in an age where informations go ramparts, if ppl won't spend a few minutes to better understand the job they are playing in any way, that's on them I say.
I don't think we need extensive training wheels that will only make us complacent, ACT, fflogs, the balance discord to new a few are avaible to everyone if ppl won't go there by themselves then there's a more intrinsical problem.

heck even a /shout can someone help me understand how [inster new skill here] works? would be a good initiative.

But if the person doesn't do that himself than it highly probable that he/she won't really improve since they have no reasons to, I might be stretching it but perhaps it relates to the low raid partecipation, some ppl aren't simply interested.
