I'm disappointed to see this is such an issue. I recently came back to the game and learned about the mentor system by spotting that crown, and then finding the mentor npc and learning about the requirements.

I typically find myself too nervous to tank higher level content, and would intentionally queue for early content in order to help new players and potentially replace a missing tank, and seeing that there was a system with a roulette specifically to help sprouts appealed to me.

Then I see on the forums that there is a mount reward and that people are flouting the spirit behind the mentor system just to get it. I may not be surprised, but I'm still disappointed, and perhaps a little concerned that the abuse will lead to the system's abolishment.
