When Materia Melders in the cities were introduced, I was thinking that it would be a great way to enhance my Level 60 gear that could take Materia. While I have been able to make use of Level 4 Materia for my gathering and crafting gear, I can't add Level 5 Materia to my Item Level 230 gear because it always says that the "item level is too low" and if it is applied to my gear there will be no stat boost whatsoever.
So knowing that I can't use Materia in gear that is supposed to be compatible with Materia, I have to ask, why give us something that we can't use?
