With the addition of CMB, there's an easy way to help out maneuver based fighters and prevent them from turning into one trick ponies (that is, prevent the lame "I trip every round" fighter build).
There should be one feat to give a +4 to CMB, period. However everytime you use the same maneuver in the same combat you suffer some penalty, either a -2 or a -4, depending on playtesting. This allows fighters to really mix it up, it's simple, and it prevents boring archetypes like the guy who does nothing but trip people.
The concept of CMB was a great addition because it centralizes maneuvers. We should take another step forward and truly combine them into one coherent category by combining the Improved Maneuver feats into one feat.
