Think of it in terms of the 4 'peasant variables'. High sympathy means that production, morale and loyalty will be high when the TO is done. High fear means low morale, low loyalty, but high control. So too much fear means a lot of diplo/courtier work when the TO is done. Too much sympathy means low control, so you need to do police work/courts when done. By playing to the middle, you get decent stats across the board.
