I haven't worn my crown since I got it, mainly because I never needed it to mentor other players and be helpful besides.

I've also noticed a sort of backlash against mentors by regular players (because of the actions of a few bad ones), so I don't wear it as a means of keeping people receptive to any words I might offer. If I'm legitimately trying to help and being patient and kind, I don't need or want to be met with venom purely for being a mentor. Further still, I understand that - in some very rare cases - people need to try and fail in order to REALLY learn what they need to learn. So a certain degree of silent support is necessary.
