I loved the sphere grid, I remember making Yuna and Auron into indestructible tanks, both able to kill any fiend with one blow. However this actually did not take away from the individuality of other characters, only much much later in the game did you have a chance to really create a hellish party.
So yeah if they bring back the sphere grid I would be very happy.
