I would change the license board so a character could gather all the spells of a certain type (i.e. White Magic) w/o having to get any spells of a different type. Let's say I was doing a challenge where only one character could get white magic & only white magic, I'd have to get (I think it's) a green license to get the higher white magic.

Also, Bolivar's idea of spreading the Technicks isn't bad.
