Nice to see people are looking forward to this. Thanks all for the Support!
And to Lemont Elwood; Not really. Well, it depends on what you want. If you have a massive country you need to rule, and you don't plan on expanding, then sure, Bureaucrats will probably be for you, this is the situation China finds itself in at the beginning of the game. However in truth, you will want to avoid giving all of the power to any single Class, because once they are at Absolute Power, although the bonuses they provide may increase sharply for a time, so too will their corruption...
Each Class will have a Corruption Rating. As this value increases, the class's Bonuses will decrease, and eventually reverse into penalties if corruption gets high enough (probably over 60 or so out of 100). And having any class at Absolute will quickly increase its corruption rating.
If you find yourself with an Absolute Noble Class with a corruption nearing say 80, you won't be getting hardly anything in tax income, force limits will be crap, morale will be low, and because the Nobles have Absolute power it will be very difficult for you to fight their power, or their corruption.
And that's the situation Poland finished the game in.
