I think a lot of the game will be determined by the 36 card Objective deck, and how that plays out. Really, a large fault of the FOC lies in the current 6 main missions, and how it values different FOC sections. Namely, how much it undervalues Troops units, except for on turns 5-7 where Troops go from being completely worthless to being extremely valuable, and how Heavy Support tends to be very valuable on all turns (because those options tend to be very killy).
Changing the missions, and tying a value to a unit beyond just what it can kill, can really impact a units effectiveness and, therefore, point value.
