What i mean is this:

You seperate character level and class level completelly.

Your character has one "primary class". They gain the BAB, hit dice, base saves, and skill points per level of this class.

As you gain XP, you gain an equal number of "CP", or "class points". Your XP advances your number of hitdice only, giving the effects outlined in the previous line.

You spend CP to advance any class you want, and you only gain from the class everything but BAB, saves, hitdice, and number of skill points. Classes other than your primary class are at a penalty when spending CP. The degree to which I am unsure of.
