Come on its not so difficult. Actually is not difficult at all. Its easier than before, at least is more interesting and now someone does not makes a rebellion with only one county cause he is pissed off by you but he tries to gather others against you. Now we get less rebellions that were just a distraction and we have a few interesting big civili wars. The old system was irrational and boring, and it wasnt easier that that now. Also before making such a statement first criticise yourself and your way of play. By the way im not a hardcore player i am a casual player who enjoies a good story telling game and not an other total war (i play a lot of total war too but they are different games and actually in my opinion CK2 is more casual and relaxing than total war)
