As stands its just an ego thing. I think certain skills/spells should be granted to players once they have reached a certain level. Ohh is that statement not going to cause outcries of unbalance and giving higher levels more stuff they shouldn't get.
Translation:
"As it stands, it's just an ego thing. Therefore, it should be ego PLUS more power. Oh, now watch the complaints as my unbalancing idea is criticized for being unbalanced."
