This wouldn't work - everyone has different expectations of what a Mentor should do. As I've said in multiple other threads, some people expect Mentor's to know everything and everything while others think they're a joke and won't even accept the help offered to them.

People also choose to become Mentor's of crafting, gathering and PvP and do not know every mechanic of every fight in the game. This shouldn't be reportable when for all you know, they've just spend 20 minutes explaining collectibles to someone.

Of course if a Mentor is clearly trolling then that's another story, but Mentor's are human too and sometimes forget some mechanics or need a reminder of a certain fight. Don't be so harsh.
