Mentors - What is expected really?

[Thamorian]

No, the Mentor Roulette was added at the same time the Mentor System was added (Patch 3.2). Any content inside that Roulette you should be required to know. This doesn't include Coil, Savage, or Ultimates, but it does include everything else.

If it did, my mistake. I remember it coming out later for some reason. But regardless, all other points still stand.
