hence you would be using your gimped attachment gear most of the time rather than your god armor of the heavens. It makes a lot of sense while your leveling, to give your new gear some boost from your old, but high level, it means wear gimp gear, equip god gear for boss only maybe.

soooo they got to figure how to balance that urge
Why do they have to balance that urge? People who don't wanna spend god awful amounts of time making awesome materia can do their thing, while the ones who do can farm all the materia to their heart's content. Conversly you can also buy and/or trade materia.

Options, people.
