Mentors...please!

[Lastelli]

Jump potions. I could jump DRK to 70, bumble my way through the MSQ, and still get to 80 without even turning on tank stance. Especially with Trusts.

Level is never an indication of skill in this game.

True, but that's again not the point here. The point is, you don't need tp be a mentor to expain the basics of the job (which was what I was arguing in the first place). If someone didn't understand the basics after leveling from 70 to 80 (which requires approximately 20 hours of play time, more than many full games), he's not the kind of player that would pay attention to what a mentor says. What's the chance of knowing absolutely nothing about you job after 20 hours of gameplay? Close to zero. Even if you used a jump potion. That's why mentors should be something more than casual players that know general info about the game and the basics of the three roles.
The thing is, there's nothing in this game that certifies your skill except for (current) savage and ultimate achievements, but that's probably a bit too much to ask of mentors.
