My problem with the current system is that characters run into an exponential wall of ice that freezes their attribute totals while still allowing them infinite skill advance.
I.e.
- 34th attribute or 1/5th of a skill point
- 36th attribute or 3/5ths of a skill point
- 38th attribute or 2 skill points
- 40th attribute or 8 skill points
- 42nd attribute or 32 skill points
- etc
The only thing stopping every character from knowing every talent and spell of IQ or less is that they die of old age first.
