I'm so against U/U gear being meldable. I would like to have different stats on my sword other than what materia can provide. Materia is very limited with what stats can go on what gear. Please do not make that the bulk of my stats come from materia on my U/U. I want my U/U to have unique stats and abilities unable to be provided by materia. For example, Ifrit Bow has Att. Pow, Fire resist, and bonus fire damage. I like this because these are not stats able to be put on a bow with materia.

Let crafted gear by empty vessels to fill with the limited materia system, let my U/U gear be pre-fill vessel with unique stats.
