Following on from what Sarapis said, there are certain high level abilities that have not been fully tested yet.

I shall take it that anyone who sits on-line for long periods of time just to accumulate lessons, is volunteering to help test these abilities out.

This is of course, only a short term situation, as Sarapis said.
