The irony here is that you blame people for not looking up a guide, reading a 10 page essay, experiencing the fight, etc. before going into it, but you clearly didn't read the rules of becoming a "Mentor" when you became one, so let me clarify what it says word for word in game when you decided to become a Mentor.

Your online status will be set to "Mentor."
Other players will be able to identify you as a mentor while this setting is active.

As a mentor, you are expected to actively perform the following:
1. Provide gameplay advice for new adventurers and other players.
2. Be an exemplar for player etiquette.
3. Invite new adventurers to the Novice Network, and answer their queries in the chat channel.

*Inappropriate mentor behavior may be reported.

Then it offers you a "Yes" or "No" option to join.

I'm not saying you're a bad player, just a bad Mentor who doesn't understand what they've gotten themselves into.
