It really depends on school of thought. TASing FFT is what brought me here, and it quickly became apparent that fastest result was solo Ramza Calculator. It is MASSIVELY OP. But if all you do is restrict it, it goes from ludicrously OP to useless, so if you don't want to retain its fecking insane usefulness in the hands of either player or AI, it's better to just kill the job off. Calculator is so difficult to balance that you really do have to choose between obscenely overpowered and laughably useless. There really is no in-between.
