"Materia-related changes in Patch 3.2
It will not be possible to use advanced materia melding for primary stats on equipment created by crafters. We will be making adjustments in the future so that advanced materia melding can be used to enhance sub-stats.

From Patch 3.2, crafted equipment will become more powerful that what it has been up until now.Furthermore, accessories will be implemented at the same time as the high-tier equipment that can be created by crafters. Additionally, materia slots will be added to raid equipment and the equipment that can be purchased with the various tomestones, so you’ll be able to add materia to boost the sub-stats that you prefer.

Many of those attempting instanced raids in the early stages tend to use advanced materia melding on accessories, which lead to tanks being required to meld STR or VIT. Due to this there were times where the melded accessories were better than the accessories which dropped from clearing the instance. In order to resolve this issue, in Patch 3.2 we will be making adjustments that will change the damage calculations of tanks into a more appropriate state.

As an overall plan moving forward, we will be making adjustments so that a burden is not placed on any particular role in order to challenge a high-difficulty raid."
