Would it be hard to throw in the hours age of the character into the mix somehow? I realize it wouldn't be realistic for an older person to learn something more quickly than a young person, but from a game balance standpoint, it may work well to do just that. So this, with the changes you've already implemented, and Isildur's idea above, you'll get:

Character's most likely to have perfect skills are those who have:
- Highest intelligence and wisdom
- Fought the most challenging fights
- Advanced furthest in their guild
- Lived the longest

... which is basically how the skill system would have originally worked had so many people not stopped to get 100%'s.
