Ok, I don't know at this point if CK2 is going to have the same 4 social classes (peasants, burghers, clergy, and nobles) as CK1, or if you'll be able to voluntarily change the relative power of each class in a county, but if you are able to do so, please make the interface work so that you can actually give more power to one class at the expense of another particular class instead of taking some from each of the others.
