What he's trying to say is what I've been trying to say before. The mentoring requirements are built around the Heavensward world rather than the A Realm Reborn world which makes the requirements bad. He has a Lv50 healer. That's enough to know all of the basics of ARR. Remember as I said earlier in this thread, the "basics" that everyone keeps repeating(basic leveling fundamentals) were built and established in ARR. But players need to go through the "fairly" long grind from 50 to 60 which has nothing to do with teaching basics because all of the tests, fundamentals, and mechanics of the game are packed in 2.x not 3.0 which reuses a lot of mechanics.

If you were a lv50 Tank, DPS, and Healer for 2 years or since 2.x release, what more have you learned about fundamentals to teach newbies as 60? Only 5 (easy)dungeons from 51-59 and 5 abilities that in no way effect basic fundamentals. Lv60 mentoring? Yeah definitely need 60s. Fact is, if were playing so long with these classes leveled, you never needed to be 60 to teach fundamentals to new players.
