I think mentors should stop excusing their own laziness and either stop doing the roulette just for the rewards if they're unwilling to do their job, or quit blaming others for their own shortcomings and help others do their best while they do their own. Multiple times i've seen a bunch of mentore, as in multiple mentors, in a duty and none of them explain jack, so their job fall on someone elses shoulders who didn't even sign up to help. They just did it because it would help everyone complete the duty and they got no extra rewards for doing it. Unlike you pompous lot, i won't say that all mentors do that, but many do. "Anecdotal evidence"? Yeah, exactly like your unbelievably unrealistic claims.
