One thought is -

Combos were nice the way they used to be with just the solid highlight.

Skills that require a miss, dodge, etc to activate should just never be lit at all unless the condition occurs. We already have a method for showing which skills we can use....the skill lights up on the bar (conditions sufficient mp, tp, etc...). Just make the miss, dodge, etc be one of these conditions that causes the skill to light up. Feint should never be lit unless I have both TP and a Miss.

Don't mix together the visualization of combos and the visualization of eligible skills to use. These are two different concepts.
