No one is made you have way too many assumptions. When I see ToP was cleared without a healer -- PVE content that's supposed to be the hardest possible in this game, that tells me that balance right now definitely needs a serious looking into. Elemental Materia was always useless yes, however that's not to say interesting Materia can't be made. Also, the main stat Materia used to have its uses even if it was limited to tanks.
