I think the two of you have different visions of what a Mentor is supposed to be. On one end, we would have people like OldTrees or vrt or Tstar? Majofa? (I'm not particularly well-versed in who would be iconic for PvP), who are iconic in their impact and knowledge of a particular subject-- OT had an entire position made just for him. On the other hand, we could have people like MMC or myself, who have some activity and achievements, but aren't particularly demonstrative of mastery in anything.
Root's better than myself (and a whole lot of other people) in pvp. If I bothered to ask and he was willing, I could probably learn a ton from him. That doesn't mean that my advice would be worthless to somebody who's started yesterday, or that somebody with a comparable amount of experience couldn't mentor a newb.
I think that having mentors unable to be part of the mentees as part of the Mentor program is a likely cause of the differences in vision here.
