Currently, it's possible to 'overachieve' in two categories of attributes. I believe this can be modified to not kill the lowlevels, but make it difficult to have 'maximum' abilities with a simple sliding scale model.
Make the max level of a skill need an extra point in the attribute, per level, starting at 2. The following chart illustrates this better:
Attribute: Max Skill Level
2 :1
5 :2
9 :3
14 :4
20 :5
27 :6
35 :7
44 :8
So, if you wanted leadership of 8, you'd have to put most of your points into being able to lead a group that big, making you a commander instead of a brawler at the end of your career, and vice versa. This scale would allow for most people to have a decent rounding of skills by 20th level (remember you start with a head start of at least level 5 or 6 in an attribute.), but you'd be forced to heavily concentrate in something to take it beyond level 4, which would be (in my mind) your average 'good' person doing something, based on the levels for horsemanship and weapon mastery.
[Edit: Addendum:
It might be found that if you're explicitly pushing a specific attribute up you end up with 'extra' skill points. These could be re-routed to further being 'attribute' points, thus you lose the skill point but can increase the attribute faster.]
