The issue with that approach, is that it further removes the focus of the party members and their abilities being the determining factors of how combat is won, and moves it to "figuring out the gimmick for that battle", which is along the same lines of the current model which also shifts focus away from the characters, and centers combat around managing the environment, like DOS.
The difference being that only 10% (or some other percentage) of all fights would have gimmicks to begin with. That would make gimmicks something special and using your abilities the default.
