I find it not all that fun to have to go several advances, saving them up, with no real change in your character, while trying to increase a characteristic.
I was thinking of allowing a player to invest a few of the points in your first career, and spend more in your next career to finish off the costs, spreading the cost of a characteristic increase between 2 careers.
Lets say a character uses up his last 2 open advances to place 2 points in strength (he needs 4 points to get his str up), he then finishes up his career. In his next career he spends the remaining 2 points, and increases his STR to 4.
Can you see any problems with this? You could still cap characteristic increase at 5 or 6, so you wouldn't have to fear them increasing something too high.
