Would consider 2 things.

One: New characters are showing that you can never be sure what substats you want, but it's worth considering that HP, defense, and Attack are all very common and easy to roll substats, so pieces excellening in those won't be rare.

Two: Elemental pieces are already out of date as the BiS for most characters. If any elemental piece isn't good for a character that already exists now, it's probably not going to matter for anyone later either. Exception to this is Quantum, which is evergreen.
