Generally, people enter the mentor system for a few reasons:
1. They want the crown.
2. They are lonely and want access to a global chat channel with a captive audience.
3. The envisioned power dynamic feeds their ego.

None of these draws bring quality people into the Network. A lot of players who have knowledge they genuinely want to share end up getting scared away from the mentor system by the weirdos dwelling within it. I see it happen like clockwork. Mentor shares accurate knowledge, another weirdo mentor "disagrees" with reality and starts a huge argument, first mentor is weirded out and discouraged.

Just the other day I saw someone try to explain that Scholar actually leans really heavily into regens and raw healing at endgame over spamming its GCD shields. Another mentor took this personally for some reason and decided it disagreed with their worldview and went on a huge tirade.
