New Mentor requirements

[Infindox]

I am to assume that after the re-certification period ends they can't access it since they will no longer meet the requirements? Didn't seem like NN was FFA, unless I misinterpreted something.

From the article:

Important
Mentors who do not renew within the specified period will be unable to access the following features:

Duty Roulette: Mentor
The ability to change online status to “Battle Mentor,” “PvP Mentor,” or “Trade Mentor.”
They will, however, still be able to participate in the Novice Network chat channel. An icon will indicate that they are a mentor who has yet to renew their certification.
