What is the point of this? I mean, I guess it doesn't hurt to slap superclass labels on things, though I have issues lumping the psion in with the wizard. But if you're going to devote space in the rulebook to it--even just half a page's worth--there should be some kind of benefit. It's not enough to show that it doesn't hurt; it ought to help in some way. I don't see how this improves anything.
