General consensus on mentors

[MirielleLavandre]

Hi all,
Been playing since beta but just now got around to leveling my tanking job to 60 -- I have always loved helping new players and have done so since long before the mentor program began, having created 'helping new players' LS and such on a couple of servers that were soon filled to capacity. My question is, now that I'm getting close to be able to be a mentor, is it really worth it? Or are mentors really as bad as they seem or as they are portrayed on the forums? I've personally only met a handful of people with that little crown who I'd consider 'true' mentors (patient, kind, willing to listen and teach). Any thoughts?

And for a newb question...what is the difference between the crown, the crown with the little sword, and such? Different requirements? I know some are DoL/DoH mentors or just PvE mentors, but never saw any different requirements, etc. and wondered since the mentor system is new (to me, a returning player). ^_^v

*Edit: I have the comms, dungeons, and other 2 jobs done already, just now finishing up DRK after coming back after a few months off*
